put a teabag in a cu and see what happens
Get a carrot. Grate and put it in a bowl/container. Add hot water and crush/stir for a while. The water should turn orange after the colour has separated from the carrot and the liquid is a indicator.Whyatt was here :D
Andrade's indicator is typically green in color. It is used in organic chemistry to test for the presence of unsaturation in a compound by changing color when it reacts with the compound in question.

An indicator. It is a substance that changes color in response to a change in pH, making it a useful tool in chemistry to visually determine the acidity or basicity of a solution.
Phenolphtalein is used as indicator for titration in chemistry. Also as a pH indicator: pink in basic solutions and colorless in acidic solutions. Phenolphatelein can be used to check blood in forensic problems or as a component of some inks.
Sodium chloride (NaCl) is not an indicator in analytical chemistry.
the answer is tea
yes
Tea is a natural indicator because it shows the pH of something on a scale however it is very basic as you will not get a full colour range.
It think that the natural ph indicator & environmental chemistry is the best option .

just don't ask me i hate chemistry.
Depending on your body chemistry and metabolism, it is possible for black tea to cause heartburn.
Anything that's "cloudy" is not a solution.

Yes. However, certain teas cannot be used. One tea which does work is black tea, which gets darker when a base is added and lighter when an acid in added.
Black tea turns red when an acid,(lemon juice) is added and blue when a base(soap solution)is added.
