Question
Give two chemical tests for nitric acid.
✓
Answer
Two tests for nitric acid are-
(i) Brown ring test :
Nitric acid in a test tube is taken and then freshly prepared ferrous sulphate solution is added. Concentrated $H_2SO_4$ is then added carefully down the sides of the test tube, dark brown ring is formed at the
junction of two layers.
