Answer 2

Yes, other plant parts can be used as acid-base indicators.

• Indicators are substances that have distinct colors in acidic and basic solutions.
• Most indicators are derived from plant pigments. A few of these are:

1. Litmus solution derived from Lichen: It is a purple-colored solution. It turns red in acidic solution and blue in basic solution.
2. Turmeric powder: Turmeric powder is obtained from the underground stem of the turmeric plant. It is yellow in neutral and acidic solution but turns reddish-brown in basic medium.
3. Red Cabbage extract: These are red in neutral and acidic conditions but turn green in basic solution.
