like it, but ive seen a better version of it where a a very sensitive universal indicator is added (or in very low concentration to the water) and its transferred from flask to flask slowly and dropped from a bit of height so allows the CO2 in the air to mix well with the water. some carbon dioxide mixes with the water and makes carbonic acid (H2CO3) which makes the solution more acidic, and overall more red after more transfers. =] and yeah, Draxis32 is right- vinegar and ammonia are weak.
omg so cool i want to do this for my science project and i really want to get an a and thanx for explaining what it does so it will make it easier for me so i can studdy it !!!!!!!!!!!!!!!!!!!!!!!Thanx
Can i use phenol-red instead of universal indicator? Would the experiment still work ?

is there a way to do this with even more colors? my chem teacher did it with I'm not sure how many, but I wanna find out how he did it.
thanks!

You can find ammonia in your pee.

Hey I can do this with the colors when I'm behind the bar :) no problem

Nice video, but NH4OH is a weak base, as well as CH3CH2OH(Vinegar) is a weak acid, that's why the colors are kinda weak too.

The colours are weak because there isn't much indicator in the flask. It's got nothing to do with how strong the acid/alkali is.

exactly... the colours would be the same strength if it was a strong acid, just a different shade

look for ammonia on the cleaning supplies aisle at the grocery store.

@HomeScience how about Universal Indicator ?

Make sure it's clear and non-foaming.
Just shake the bottle in the store. If it doesn't make suds, get it.
