Answer:-

Indicators are chemicals used to determine whether an aqueous solution is acidic, neutral, or alkaline. Some examples of natural indicators are red cabbage, turmeric, grape juice, turnip skin, curry powder, cherries, beetroots, onion, tomato, etc. Some flowers like hydrangeas can determine the acidity or basicity of the soil.
