Litmus paper and phenolphthalein are examples?

Answer 1

the actual answer is that litmus is an example of an indicator because... if for example you dip a blue litmus paper into lime juice (an acid) the litmus paper will turn red because it indicates that its an acid or......... if you dip a red litmus paper into a base it will turn blue because it indicates that it is a base..... so the answer is because it indicates if its an acid or base

p.s. if the blue paper turned red---- indicates its a base

if the red paper turned blue ----- indicates its a acid or the other way around forgot... :/

hopes this helped........ :)))))))))))

Answer 2

Litmus paper and phenolphthalein are examples of acid-base indicators. Litmus paper changes color in response to the pH of a solution, turning red in acidic conditions and blue in basic conditions.
