Question

result of nitric acid on litmus paper, china rose, phenolphthalein and turmeric

​

Answer 1

Answer:

Nitric acid reacts with metals, but the details depend on the concentration of the acid and the nature of the metal. Dilute nitric acid behaves as a typical acid in its reaction with most metals.

If turmeric is added to an acidic solution, it stays its usual yellow colour. Add it to an alkaline solution, however, and it changes colour from yellow to red.
