Question

How do indicators react with acids and bases?

Answer 1

Answer:

Acid - Base indicators (also known as pH indicators) are substances which change colour with pH. They are usually weak acids or bases, which when dissolved in water dissociate slightly and form ions. ... At low pH values the concentration of H3O+ is high and so the equilibrium position lies to the left.
