Statement 1 : A solution of Ni(NO3)2 is electrolysed between platinum electrodes using current of 5 A for 20 minute. The weight of Ni deposited is 1.825 g.Statement 2 : The mass of substance deposited during the electrolysis of an electrolyte is inversely proportional to the quantity of electricity passed through the electrolyte.

Electricity used  = 5 x 20 x 60 =.6000 CNi(NO3)2+2H++2e-2F→  Ni58.7 g+2HNO3Charge required to deposit 1 mole     Ni = 2 F = 2 x 96500 = 1.93 x 105 C1.93 x 105 C of charge produce Ni = 58.7 g6000 C charge will produce Ni=58.7×6000 C1.93×105=1.825 gAssertion is true but reason is false as mass of substance deposited is directly proportional to the quantity of electricity passed.
