Answer 2

Answer:

Indicators are chemical compounds that tell us whether a substance is acidic or basic by changing its colour. The indicators that are obtained from plants are known as natural indicators. A few examples of natural indicators are turmeric, china rosa, red cabbage and grape juice. Some flowers such as the hydrangeas can also determine whether a substance is acidic or basic. Hydrangeas turn blue if the soil is acidic, purple if the soil is neutral and pink if the soil is basic. The colour intensity depends on the amount of acid and base present in the soil.

Universal indicators are a mixture of organic dyes that give different colours at different concentrations of hydrogen ions in solution.pH paper or solution is an example of a universal indicator.
