pH indicator definition for people doing chem hw: A chemical compound that is used to visually determine if a solution is acidic or basic. Normally the indicator changes color depending on the pH of the solution it is testing.
Fantastic😊 for how long will the colours remain.. Please share how to prepare various transparent liquids with various colours to retain their unique colours in different glass bottles, for long periods
The Sci Guys It was ok - thank you guys!! Got more of it yet to do tomorrow... :SJust checked out your video again...Going to look to see If you have any chemistry ones :D thanks !!X
kalyna McCool We do have a bunch of chemistry videos. You can also find our videos on our website www.thesciguys.ca and you can filter our videos by type of science.
Wow I feel so much better about myself... I look at the comments thinking I’m the only one here watching this video for my science project but literally everyone here is doing science homework.
Add a dash of thermodynamics, and one might have a homemade snow-cone coloring recipe, if that fridge has a freezer. The blender is already accounted for... Also, french press filtration, maybe? I'm thinking of grapefruit and orange juice derivatives as a pH spectrum.
Do you think there is any way you could add anthocyanin into a plastic and if so could that plastic change colour if dipped in say lemon juice or would the plastic compound prevent the colour change? Finally, using the plastic example is there any way you could reset the indicators reaction with the solution so that you could use it multiple times? Thanks, great video, very helpful.
I did this many years back, with several household items that I thought would be acidic or basic. Most gave what I expected, the lemon juice was acidic, the water was neutral, and the baking soda was basic. And most of the other items I used also changed the indicator like I expected. But one thing confused me. I put liquid hand soap in one of the samples and I saw no change whatsoever. I expected it to turn blue but it didn't. Is it cause the PH, while basic(at least, I'm pretty sure it's basic), is too close to neutral for this indicator, that I'd need something like universal pH paper to detect subtle alkalinity like the soap?
2. Prepare red cabbage extract. Use it as indicator to classify substances at home as acid and base. ( lemon juice, pineapple juice, bitter gourd extract, water gourd extract, turmeric, detergent etc.) i want that bro will you plz tell me the steps to do it
@@c0m3t19 Even in January 2021 people are still using this video for online work, seems to me teachers like to use any lessons already made even though they might have lost relevance over time which is very annoying since most of these don't get to the point immediately or effectively and now I'm wasting my time looking for facts about acids and alkalis even though I'll forget about the information in about an hour to a week!
Hi Sci Guys- how far in advance can I make the cabbage juice indicator? Does the strength of it degrade over time if I keep it in the fridge for a few days? Also- can I use hydrogen peroxide for this experiment? Thanks!
+Talia Steiger I think it should still work but because it's a food product without any preservatives make sure you put it in a sealed container before putting it in the fridge. You should be able to make it the night before or day before and it should still work. If you're concerned, test it out on a small batch prior to doing it with the kids it to see if you still get strong results from a day or two old solution.
The Sci Guys, why did you use 4 cups of water for the experiment? Like what is the basis for measuring how much water we will use? Is it how many grams of red cabbage you used? I really need help and thanks for the video. :D
At 4minute23; your text has OH+. I thought that should read OH-. At 5minute22, you have reversed the order of acid and base compared to the graphic shown earlier. Thank you for the video.
can I use general indicator pH scale as a reference to indicate these solution pH in this experiment; or we have to use pH scale for Red cabbage indicator?
Awesome experiment but I don't get something. So if if a pigment turns red when adding a liquid ( for not just a cabbage but any other pigments), is dat considered to be acidic? Is this why litmus paper changes red to Indicate acidic. So if a pigment turns blue or like really yellow does that indicate dat the solution is basic? Is this why litmus paper changing yellow indicates a basic solution? Other than that I plan on doing dis experiment one day
Hi! Any idea as to how we could draw a graph showing the pH values of different solutions i.e. If we've got some solutions with known concentrations, and we add this indicator to obtain a set of colours. Thanks.
Dear SciGuys, thank you for this excellent video. Please note that you are using the words "strong" and "weak" incorrectly sometimes during this video. For example, you have described ammonia as a strong base, and this is wrong. In chemistry, "weak" and "strong" are technical terms that have little to do with the actual pH. "Strong" bases form OH- ions in water at a rate of 100%: every single molecule or formula unit of a strong base forms one OH- ion in water. Ammonia is not a strong base because for example if you place 2.0 grams of ammonia molecules into 1.0 liters of water, you will only get about 1.2% of the ammonia molecules to ionize the water to form OH- ions. Of course, if you put a lot of ammonia molecules into the water the pH will rise a lot, but the pH rise does not make ammonia a strong base, technically. In other words, the amount of hydroxide ions that are generated does not determine whether a base is labeled as strong or weak. Please read more on this topic at the UC Davis Chemistry Wiki site: chemwiki.ucdavis.edu/Physical_Chemistry/Equilibria/Acid-Base_Equilibria/4._Strong_and_Weak_Bases Thank you for your great work and for your time. -glen chung, chemistry laboratorian, East Los Angeles College
Glen Chung Glen Chung Hi Glen, thank you for your thorough comment. We understand our comment and appreciate you took the time to watch and comment. Our target audience is around the elementary and junior high level of science understanding, which is somewhere around the ages of 7-14. Writing the content to our videos is a delicate balance between having the info be approachable and being accurate as possible. Too much detail and we risk of the younger audiences not understanding the science and too little and we run the risk of being wrong. Our main goal as a channel is to excite younger viewers about science and give them a starting point for the science so they want to learn more. This is the same with your previous comment, in this video we are using those terms to describe the pH level of a solution. Getting into what you described is a higher level curriculum like high school. At the end of the day if a viewer watches our videos and is able to explain what is going on at this curriculum level and they didn't understand it before, then that is a win for us. If we develop a series of videos explaining the higher curriculum grades of science then the explanations will probably look different and the video will be explained why.
Hello Sci Guys. Although you've said you described ammonia as a strong base was only to make it easy for children to understand and to arouse their interests in science, it is still not correct for you to make such a misconception. If the children who watched your video believe that ammonia is really a "strong" base, they may be very confused when they learn the real properties of ammonia. Therefore, I think it is recommended for you to change 'Ammonia is a strong base...' into 'Ammonia is a weak base...' or simply 'Ammonia is a base...'. Hope you could really consider this well.
One of my favourite experiments as it's pretty much fool-proof yet the results are fairly dramatic. I have mixed feelings about how the experiment is carried out. I can see lab coats, safety glasses, gloves etc. teach proper lab safety from the get-go, which is fantastic. However not everyone has them, and likewise coffee filters and distilled water (while setting a useful base line) might not be available to everyone. If it's about instilling a sense of wonder, this is one experiment that can be simplified considerably, making it more accessible to anyone.
I will be conducting this test in Haiti where red cabbage does not grow naturally.... Are there any other vegetables or fruits that could possibly replace the red cabbage... like tropical/Caribbean fruits/vegetables?
Sarah Schulkins I just did a search and here are some ideas from a website I found. chemistry.about.com/od/acidsbase1/ss/Edible-Ph-Indicators-Color-Chart.htm
+Aditya Juneja I am not sure why water was green. If using red cabbage as the pH indicator then it should be close to neutral. That is unless something has contaminated it.
Hello Sci Guys. At 5:04, you mention that acids flood the solution with hydrogen molecules. Please note that this is incorrect. Hydrogen molecules are H2, and take the gas phase under normal household conditions. I think you mean to say that you flood the solution with hydrogen ions, H+. Some chemistry books and teachers prefer to refer to hydronium ions, H3O+ rather than hydrogen ions. Thank you for your clean, professional videos. Please consider making these technical corrections for the future. Thank you again. -glen chung, chemistry laboratorian, East Los Angeles College
Glen Chung Hi Glen, thank you for your thorough comment. We understand our comment and appreciate you took the time to watch and comment.

Our main goal as a channel is to excite younger viewers about science and give them a starting point for the science so they want to learn more. Specific to your comments, the reason we didn't mention hydronium or call them ions is because those two subjects require much more explanation about what they are than what is needed for this age group's curriculum. In the curriculum where we live, those topics are not usually touched on until the higher levels of chemistry in high school. Calling them molecules is a way of helping children to understand there is something smaller going on and may not be perfect for higher level understanding of these processes or reactions but it's still technically accurate and works great for the age groups we are targeting. At the end of the day if a viewer watches our videos and is able to explain what is going on at this curriculum level and they didn't understand it before, then that is a win for us.

the ph scale is red is acid,green is neutral and purple is base right? why some base is green/yellow and neutral is purple? what is the different in this ph scale?
Hannah Pate Well if you had a container of stomach acid, you would pour some of the pH indicator in until the colour change stops. Then compare that colour to the colour of another tested liquid that you know the pH of and it should be around that pH. Hopefully :)
HI Sci Guys, can you PLEASE make a video about the viscosity of liquids and measure their flow rates. Last time you did density now, this time you should do viscosity. PLEASE do that experiment ! Thank you
Hi Daiyan Mahfuz That is a GREAT idea!! We will add this experiment idea to our list of experiments. We have the next 2 or 3 experiments already prepared but we will add it to our current schedule of videos as soon as possible. We really appreciate you submitting this idea and THANK YOU!!
