10g fairly concentrated solution of CuSO4 is electrolysed using 0.01F of electricity.calculate::


(a) The weight of resulting solution. (b) Equivalent of acid or alkaline in the solution.

According to Faraday I lawW=ZQZ= electrochemical equivalentW=weight of the substanceQ=It = current × time1 Faraday current deposit 63.52 = 31.75  g of copper0.01 Faraday current deposit  31.75 1 × 0.01 = 0.3175 g of copperSolution weight (initial) = 10 gAfter electrolysis weight of the solution= 10 - 0.3175 = 9.6825 gb) Equivalent of the acid = Charge = 0.01
