Question

The metal which will not produce hydrogen gas on reacting with dilute sulphuric acid is:
A. sodium
B. silver
C. iron
D. zinc

Answer 1

answer is option b

Ag means silver

Ag is less reactive then so4 so reaction can not be taken place here

Answer 2

B. silver

Explanation:

Silver does not react with dilute hydrochloric acid and dilute sulphuric acid. But, silver reacts with hot concentrated sulphuric acid and this reaction gives sulphur dioxide water and silver sulphate. Silver reacts with both dilute and concentrated nitric acid to form silver nitrate.

Sodium, Iron and Zinc reacts with dilute sulphuric acid to form the respective sulphate and hydrogen gas is evolved.

Option B is the answer.
