actually the reading should be from top to bottom so it is 10.3...something (can't estimate the last digit going from our angle)... not as described by the narrator.
1.determination of titratable acidity of 100 gm orange juices? What is the principle , raw materials, instrument and equipment , reagent, method, and calculation??? Please make video on this question
When using this reaction it should still be molecular weight of citric acid used in the last part of the numerator of the equation. The molecular weight of citric acid is 192.124g/mol. The reaction ratio (mol/mol) is a 1:3 ratio of 1 part citric acid reacts with 3 parts sodium hydroxide
Wait a second... am I helping you cheat on a quiz?! :) For wine, the prevalent acid is tartaric acid. H2C4H4O6 + 2NaOH → Na2C4H4O6 +2H2O For lemonade, the prevalent acid is citric acid. p.s. Hope you get an A!
Hi Demar. The lower the pH reading, the more acidic the sample. In this situation, determining which sample required more titrant will tell you which sample is more acidic.
@@HannaInc Thanks for replying, I got an assignment to test two orange juice to check which would have the highest level of acidity, so hence my question. Is there a specific method I could use in order to get the best result?
@@Iam...demetriuss If you're just looking for the most acidic juice, a pH reading will give you your answer. If you're trying to determine the amount of acidity, a manual titration like this would be the best way to do it. The lower the pH reading, the more acidic the juice is. All you need to get a pH reading is a simple pH tester. If doing a manual titration, use your pH tester to get your starting point, and use sodium hydroxide as a titrant. Add drops to the juice until you reach an end point of pH 8.2. Record how much titrant was used for each sample, and determine the amount of acidity by using the equation in this video.
Hanna Instruments, Inc. I wish I could show you the initial p&d I draft for this. I did actually use ph test but my teacher told me this option was way too easy so I couldn't use it. Now I'm trying to do it over again using titration.

Jeez this was painful to watch. Did someone take this poor girl hostage and make her do this video?

I've only taken one chemistry class in my life but I think that young lady is reading her burette incorrectly.
How did you get 10 as the conversion factor? Thank you!
Srsly was she kept at gunpoint to do this vid. She looks as if she is gonna cry soon and run going mommy
Thanks for this!
What is the chemical formula for this experiment???
but the way described by the narrator still works as it is the volume of NaOH delivered that is what she is looking for....
When do you know that the titration ended?
10ml of orange juice in how much ml of distilled water
In the formula, is it mol wt or equivalent wt of citric acid?plzz rply..I have found eq wt

what's the citric acid equation? Is it. C6H8O7 + 3NaOH -----> Na3C6H5O7 + 3H2O ???
Thank you so much, can you please tell me what equation I should use for white wine and do I use the same citric acid equation for lemonade??

Hanna Instruments, Inc. omg thank you so much I have this lab report and you just saved my life😭❤️❤️
So what if you were testing two different orange juice, how would you know which one is more acidic?
Hi Demar. The lower the pH reading, the more acidic the sample. In this situation, determining which sample required more titrant will tell you which sample is more acidic.
