Question

what is an indicator? can you prepare any natual indicator?

Answer 1

⇔Natural indicators relate information by demonstrating shifts in color to inform observers of whether materials are acidic or basic. The indicators, which are plants containing useful chemicals relative to pH levels, do not provide a numeric value for acidity or baseness. Common natural indicators are litmus, red cabbage and Hydrangea. 

⇔I will provide some steps to make a indicator using beetroot.

⇔ First juice two or three beetroots and peel off. Then make juice out of these beetroots and filter it. Then drop filter paper strip into the juice. Let it be dry.

⇔ THIS DRY FILTER PAPER ACTS AS AN INDICATOR.
