Question

If hydrogen gas is evolved when nitric acid react with zinc granules

Answer 1

Zinc is more reactive than hydrogen and it displaces hydrogen from dilute acids. Zinc reacts with dilute sulphuric acid to form zinc sulphate and hydrogen gas is evolved. This is a single displacement reaction of a non-metal by a metal.

Answer 2

This activity studies the reactionbetween metals and acids by dropping some zinc granules into dilute hydrochloric acid and dilute sulphuricacid. ... In general, a metal reacts with an acid to form a salt and releaseshydrogen gas.
