Answer 2

Acidic or basic dyes are used as indicators in which titration method​.

Explanation:

• Acidic or basic dyes are used as an acid-base indicator.
• It is either a weak acid or weak base that exhibits a change of color as the concentration of hydrogen ($H+$) or hydroxide ($OH-$) ions changes in an aqueous solution.
• Acid-base indicators are most often used in titration to identify the endpoint of an acid-base reaction.
• The best-known pH indicator is litmus. Thymol Blue, Phenol Red, and Methyl Orange.
