    Default Really random!!

    I know this is really random but they dont have an off topic thing so I had to post this. And i have a lab due tomorrow.

    Here is the problem: How can indicators be used to gain information regarding the pH of aqueous solutions?

    I need a good conclusion on this one. If anyone will help I will love you forever. Thanks

    Color change of a litmus paper can provide different results. One color for acidic, one color for basic, and stays the same color for a pH of 7 (neutral).

    Chemical solutions can be used as well ie: phenolphthalein and thymolphthalein..

    Bases turn litmus paper blue.
    Acids turn litmus paper red.
    Phenolphthalein turns a base red.
    Phenolphthalein is clear in an acid.
    Thymolphthalein turns an acid red.
    Thymolphthalein is clear in a base.
