If 5 ampers of current is passed for 193 seconds through a solution containing Copper salt, 0.32 ~g of copper is deposited. What is the oxidation state of the Cu in the salt?

Options

  1. A+2
  2. B+1
  3. C+3
  4. D+ 3 2

Correct answer

A. +2

Step-by-step solution

Charges passing through solution =5 193=965 C Cu ^ n + + ne Cu 965 C charge deposit 0.32 ~g aligned & 96500 n C charge deposit = 0.32 96500 n 965 =63.5 & n 64 32 =2 aligned
