Options

(A)Same amount of H2H_2 gas will be evolved.
(B)H2H_2 gas will not be evolved.
(C)The amount of H2H_2 gas evolved is less.
(D)In place of H2H_2 gas, O2O_2 gas will be evolved.

Official answer

Same amount of H2H_2 gas will be evolved.

Answer keywords:Same amount of H2H_2 gas will be evolved.The amount of H2H_2 gas evolved is less.H2H_2 gas will not be evolved.In place of H2H_2 gas, O2O_2 gas will be evolved.

Marking scheme

  1. 1.Same amount of H2H_2 gas will be evolved.
  2. 2.The amount of H2H_2 gas evolved is less.
  3. 3.H2H_2 gas will not be evolved.
  4. 4.In place of H2H_2 gas, O2O_2 gas will be evolved.

Hint

The reaction between zinc and an acid produces hydrogen gas. The type of acid used does not affect the amount of hydrogen gas produced.

Quick oral answer

The reaction between zinc and an acid produces hydrogen gas. The type of acid used does not affect the amount of hydrogen gas produced. Therefore, if acetic acid is used instead of dilute sulphuric acid, the same amount of hydrogen gas will be evolved.

Common mistakes

  1. 1.The amount of H2H_2 gas evolved is less.
  2. 2.H2H_2 gas will not be evolved.
  3. 3.In place of H2H_2 gas, O2O_2 gas will be evolved.

Analysis and explanation

The reaction between zinc and an acid produces hydrogen gas. The type of acid used does not affect the amount of hydrogen gas produced. Therefore, if acetic acid is used instead of dilute sulphuric acid, the same amount of hydrogen gas will be evolved.

Interesting facts
