1 C electricity deposits

Options

  1. Ahalf of electrochemical equivalent of Ag
  2. Belectrochemical equivalent of Ag
  3. C96500 g of Ag
  4. D10.8 g of Ag

Correct answer

B. electrochemical equivalent of Ag

Step-by-step solution

From Faraday's first law, Mass deposited, W=Z Q when Q=1 C , then W=Z= electrochemical equivalent.
