Problem
An electric current is passed through two solutions of (i) AgNO3 and (ii) a solution of 10 g CuSO4⋅5H2O crystals in 500 mL H2O , platinum electrodes being used in each case. After 30 minute it is found that 1.307 g Ag has been deposited. What was the conc. of Cu expressed in g of Cu per litre in solution after electrolysis? (Atomic mass of Cu = 63.54, Ag = 108)
