Two voltameters one of copper and another of silver, are joined in parallel. When a total charge q flows through the voltameters, equal amount of metals are deposited. If the electrochemical equivalents of copper and silver are z₁ and z₂ respectively the charge which flows through the silver voltameter is

Options

  1. Aq 1+ z₁ z₂
  2. Bq 1+ z₂ z₁
  3. Cq z₁ z₂
  4. Dq z₂ z₁

Correct answer

B. q 1+ z₂ z₁

Step-by-step solution

q₁ Z₁=q₂ Z₂q=q₁+q₂ q₂= q 1+ Z₂ Z₁
