Is an organic compound that changes color in an acid or base?

Answer 1

This might not be your answer, but universal indicators change colour when they come in contact with a substance. It will then change to the colour of its corresponding pH. So, in terms of bases, it turns from a turquoise (from green which is pH7) to a dark purple the more alkaline it is(<7-14) and in terms of acids, it goes from a green-yellow to a dark red (>7-0).

Answer 2

An acid-base indicator is an organic compound that changes color in response to changes in pH. It typically exists in different colored forms depending on the pH of the solution, allowing it to be used as a visual indicator of acidic or basic conditions.
