![]() ![]() Chemicals with a low pH (0-6) are acidic, while those with a high pH (8-14) are basic. (A pH of 7 is neutral: neither acidic nor basic.) Universal indicator is a chemical that changes color in the presence of acids and bases from a pH of 2 to 10. The secret of this magic color change is pH. Slowly pour the contents of the first flask into the second one, then the second into the third and the third into the fourth. Put 100ml of vinegar in the fourth flask.ĥ. (Be very careful not to breathe in the strong fumes from the ammonia!)Ĥ. Add a dropper-full of ammonia to the third flask. In the second flask, put a dropper-full of vinegar.ģ. Put 25 drops of universal indicator into the first flask, and then add 200ml of water.Ģ. Four 250 ml erlenmeyr flasks or 250 ml beakersġ.See this experiment in action before you try it!
