Answered by waghumbareshraddha20

Explanation:

Indicator Colour in Neutral Medium Colour in Acidic Solution

Litmus Purple Red

Turmeric Yellow Yellow

Red cabbage leave extract Red Red

Flowers of hydrangea plant Blue

pH indicators detect the presence of H+ and OH-. They do this by reacting with H+ and OH-: they are themselves weak acids and bases. If an indicator is a weak acid and is coloured and its conjugate base has a different colour, deprotonation causes a colour change
