The pink thing is pink because of phenolphthalein.. You may have already mixed it up with the alcohol solution but as it show no colur in neutral and acid so it's there but we just can't say that as it's colourless but after dissolving that base salt in that it turned out pink.and that salting out thing happened..I guess the phenolphthalein is mixed with the whole solution just not with the alcohol solution in the last. but as it's colourless we can't tell whether or not it has mixed.
erbium came to mind first, but this ain't liquid glass, and that shade looks more like vanadium... so I need to get more familiar with the indicator solutions....
This is fascinating. Made sense that a pH indicator was involved, but the salting out threw me for a loop. I must’ve watched the short about 20 times. 😂 Thanks for sharing, TT!
Maybe Phenolpthalein as it indicates alkaline (base )by changing to pink so at the end when have thymol blue dissolved in alcohol solution and Phenolpthalein pink?
With every video I watch I remember a different chemistry lesson and I don't know if that is a good thing or a bad thing since I enjoy learning chemistry, buuut it's quite complicated.
@@TommyTechnetium I did many dye tests for layer separation (water and acetone in my case), and I tried some indicators. I can confirm phtaleins color the water layer. You use Yamada indicator?
I see, now this makes a lot more sense as isopropyl alcohol but I knew there was a pH indicator like thymol blue. 😊I didn’t see the Potassium Carbonate part of it though, but it makes 100% sense now! 😅
Hey i have a dout If we put solituion of acid alcohol blue ,red ,yellow and salt then it is fromed a yellow colour .ok and if we put that mixture of soliution in to another beaker then it turn red fluid an then again we put the red coloured solution in yellow fluid then what happen it turn into white or black ??
Hi Tommy if i use phenol red 8grams into 100 grams of water it should be soluble and turn orange right? If i place this sution into the bydrochloric acid , it should tuen the solution yellow in the test tube as an acid, but what can i use as a substitute for the potassiun carbonate to allow the addition of the bade to " salt out"? And settle to the bottom?
@@TommyTechnetium no not at the moment how would sodium bicarbonate react within the test tube once the hydrochloric acid is placed in, I know it will produce Carbon Dioxide Gas and keep in mind I'm using phenol red tat should turn more orange mixed with water in the flask using the right proportions then the phenol should turn yellow in the test tube with the HCL but what is your Thoughts on adding the baking soda into the test tube and shaking the test tube ...I would think it would at link turn it a shade of pink ...the NaCHO3 has a density of 2.2 , the phenol red about half then that but I don't believe I have a salt.....now I do have Sodium Hydroxide Solution but its not a solid? Your knowledge please????? I want it to be able to "Salt out"
@@capristhebomb indeed, sodium bicarbonate will produce some CO2, but sodium carbonate does as well. I'm not sure what will happen; give it a test and let me know what happens. If you'd like a salting out demo with simple materials see ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-juaI71v050A.html
Recent chemistry undergrad here, completely whiffed on the salting out bit. Dont recall if that exact phrase was ever used, but thinking about polarity and density and their effects on solutions/emulsions mixing or separating was definitely rigorously taught. Guess i let down my alma mater on this one! 😂
Hey, you were thinking about polarity, solutions, emulations, and density while trying to figure this out...that's enough to make any chemistry program proud of you 👍🏻
You added phenolphthalein to the thymol blue As you have said,pottasium carbonate is a basic salt and when it dissolves, a basic liquid forms. When shaked,the phenolphthalein can come out from the blue colour. As phenolphthalein is denser than isoprophyll alchohol,it will sink down Hi Tommy sir! I am a child chemist of age 13. Hope you liked my guess. If it is correct, please reply me These all are from my observation of phenolphthalein Thank you
Very well thought out! The phenolphthalein ends up in the water layer because it is more soluble in a water based solution of potassium carbonate than in alcohol
It looks fun, but I recommend against doing this at a science fair. This experiment involves strong acids: 6 M hydrochloric acid. This stuff is pretty dangerous. A science fair usually doesn't have the required safety equipment should it go wrong and you spill some on yourself, or worse, someone else. You might be able to do something with acetic acid, which is a lot safer, but you'll need to research it yourself. I can also explain what happens here if you want
I think you can do it with different chemicals. And they should be safe too just don't drink them. For the pH indicator you can use red cabbage water. For the acid use vinegar. For the alcohol it's the same just use isopropyl alcohol. And use baking soda instead of potassium bicarbonate. I'm not sure if it's going to work but I think it should. Follow the same stuff they did in the video and it should hopefully be good.
I'd like to know the size of the test tubes, beakers, and flask used in the video. I would love for this to be my first experiment, because it's the only one i can find that isn't dangerous. (Besides the HCl, but I will have proper safety equipment.)
I mean... in the first place I guessed that the last step was some sort of centrifugation, but it would be really odd to centrifugate anything doing that ... I'm kinda lost here.
I agree. I think he is using the wrong term here. Salting out usually refers to when 2 compounds compete for solubilization and the lesser one crashes out of solution.
Bachelor chemistry student here, this is my thought: The organic solvent, the alcohol, is thrown out of solution because the salt is more soluble in water and saturates it, thus the alcohol takes the pH indicator with it since the pH indicator is poorly soluble in water
@@urheadset3584 Thank you for the explanation. But one quick question. Is the basic salt used here soluble in the alcohol too? If not, then the top alcohol layer should be yellow instead of blue, right?
