Question

1 litre of 1 m coppersulphate solution is electrolysed after passing 2 farad charge the molarity of copper sulphate will be???

Answer 1

For 1 M CuSO4 soln.,

moles x valence factor = q/F

Therefore,

1 x 1 x 2 = q/F

q = 2F

Therfore for passing 2F charge would consumed the soln. completeley and hence the Molarity becomes zero perhaps!
