great video👍
Thank you so much. I couldn't find any vidoes on this.
this so fye if you wanna learn how alcohol is made. pretty much the gist of it!
But temperature is already same for different number of particles
Muchas gracias, no encontraba como hacerlo :)
That is not the proper procedure for making solutions for your standard curve. You do dilutions from the one before not measure ou different volumes from the 0.4 M solution.
Huh. What’s the difference?
Physics teacher here ... Help me out??? WHY does my data "flatten out" once my pendulum get longer than, about, two meters? Thanks ... Scott Forbes
The period is dependent on the square root of the length. If you y=x^(1/2) on a graphing calculator, you will see a very similar shape.
Thank You so much it was Very Helpful
if we made fermented drink and we want to destil that mean at 65°c will come out methanol first right? and at 78°c will come out etahol ? am i right? because i got some question if i do destile i need to do at 65°c for a while or just do at 78°c instead? thanks you
Yes, but still don't drink the product from the first 5 minutes or thereabouts after the temperature has switched. And also keep an sharp eye out for the NEXT temperature increase, which is when the water's about ready to boil off. There are toxins at that end, as well. My friend who distills says he uses a number of containers to catch the product (distillate) during his distillations, one at the beginning to catch the methanol, which he switches out to a new one after 5-10 minutes of catching it once it rose to the Ethanol Temperature. He then proceeds to switch out every half hour or so, keeping an eye on the speed of the drips. When the drips start slowing, he marks that container as the last. Once the temp spikes to 212F/100C, you're getting water. After he is done, he uses a sensor to detect the levels of methane in each container, and, if too high, he drops all that product back into the still for another run. He is dreaming of the day he can get a proper Fractional Distillation Column like those shown in these videos so he can get 95% pure Ethanol Motor Fuel in one run. So do I. I'm doing destructive distillation of wood, FOR the Methanol. I want pure methanol. Be very cautious if you are distilling Ethanol for drinking. Being poisoned by Bad Hooch is a large part of why America has an ATF. Death by Waragi is real, and not fun. Everyone I know who brews is more anal retentive about sterility than Doctors are.
@@TimeSurfer206 thanks for your information that help a lot
How do you know the temperature of the water is the same temperature as the water? Is there a way to gather evidence that the water is the same temperature as the vapor?
Great idea to have this; I think it's be helpful.
Great video, thank you for this tutorial!
What size this tube??
✨ 𝕡𝐫o𝕄o𝔰𝓶
Super underrated tutorial, thanks so much for this. Such a lifesaver.
👍
Fantastic video bro .....by the way I'm also making Diy and Arduino projects please see 😃
Thank you sir
Thank you for this video.. Please.. Can the same experiment be used to determine urinary copper?
That’s outside my area of understanding, but if it makes a colored solution it seems to me that Beers Law would apply just as well as it does here. You’d have to have a way to get known concentrations for a calibration plot or be able to look up a molar extinction coefficient I’d think
Cool video

You cannot separate water and ethanol completely. They form an azeotrope due to the hydrogen bonding between water and ethanol. This causes the coalescence of the boiling points to single temperature.
Yep. But this video is made for 10th graders, so I over simplified my narrative. There still is significant separation, as the ignition test at the end shows.
@@Mrscrapiron5 makes sense, 90% of all the distillers i've met doing tours in rum and whiskey distilleries don't understand how distillation of ethanol actually works. so i don't think a 10th grader would understand much better
Yes you can. Never say can't when dealing with chemistry..... you'll be incorrect often. There are several ways.
@@Mrscrapiron5 Uhhh, cool but azeotropes are a concept typically taught in 10th/11th grade curriculums...

Thank you! This really helped :)
Tysm this helped me a lot
Thank you for the video, but I want to know if I could change the significant figure (more decimals) of that slope and intercept in Google Sheets.. do es enyone know how to do it, please? (i.e. m=2.8924 insted of the given 2.89)
THANK YOU
I like your explanation I want it to do it every time i change it and when I refresh It will sort the entire sheet
Thank you this helped save me time
Thanks!
very good sir, THANK YOU
Thanks
it is so valuable if you could add more clear video and do it with more details.
Thanks you very much
HERE'S JOEY!!!
You are amazing. Thank you so much!
Exactly what I had to do in my Cost Accounting class because Office 2011 doesn't have the regression tool that you can download in the analysis tool pack on PC. i am guessing that mac 2016 has it though!
thank you!!!
This is for Danny Garside. I got an email about your comment, but I don't see it here. Anyway, you said "Would love to see a description of what's happening here" This is a good explanation of how the demonstration is set up: ua-cam.com/video/vqyuLEGrZcs/v-deo.html This is a bit more detailed explanation of the chemistry behind the demonstration: ua-cam.com/video/WRcE3-oKBFs/v-deo.html
you made this very simple. thanks
Thank you! Everywhere else I was looking said I had to download a package to get a line of regression.
Thank you so much ! That helps a lot ! :)
Thank you very much for this thorough video!
You're very welcome.
Thank you! Saved my homework.
We have been watching your ch5-6 and 10 videos lately and in my opinion your videos are really helpful! Thank you for the efforts you put into these videos!
Glad you are finding them useful. Feel free to ask questions or make comments.
You are my HERO! Save me, my time, and my homework! :D
Thank you. Thank you. Thank you.
