What is the charge required for the reduction of two moles of Cu ²⁺ to Cu ?
Options
- A2.89 10^5 C
- B1.93 10^5 C
- C9.65 10^5 C
- D3.86 10^5 C
Correct answer
D. 3.86 10^5 C
Step-by-step solution
aligned & Cu ²⁺+2 e ⁻ Cu & 1 ~mole 2 ~mole ⁻ & 2 ~mole 4 ~mole ⁻ & Charge of 1 ~mole electrons =96500 C & Charge required for the reduction of two moles of Cu ²⁺ & =4 96500=3.86 10^5 C aligned
