A current of 1.6A is passed through a solution of CuSO ₄ . How many Cu ⁺⁺ ions are liberated in one minute? (Electronic charge =1.6 10⁻¹⁹ C )

Options

  1. A3 10²⁰
  2. B3 10¹⁰
  3. C6 10²⁰
  4. D6 10¹⁰

Correct answer

A. 3 10²⁰

Step-by-step solution

Charge flowing in one minute q=I t=1.6 60 C Charge required to liberate one copper ion 2 C Number of Cu ²⁺ liberated = 1.6 60 2 1.6 10⁻¹⁹ =3 10²⁰
