`100mL CuSO_(4)` (aq) was electrolyzed using inert electrodes by passing `0.965A` till the pH of the resulting solution was 1. the soluton after electrolysis was neutralized treated with excess `KI` and titrated with `0.04M Na_(2)S_(2)O_(3)`. Volume of `Na_(2)S_(2)O_(3)` required was 35mL. Assuming no volume change during electrolysis calculate:
(a) during of electrolysis if current efficiency is `80%`
(b) initial concentration `(M)` of `CuSO_(4)`.

A
