(1) The same quantity of electricity is passed through 2voltameters connected in series, one copper voltmeter with copper electrode in a copper(ii) tetraoxosulphate(vi) solution. The other platinum electrode in a dilute solution of tetraoxosulphate (vi) acid. 500cm³ of dry hydrogen gas measured at 20°C and 720mmHg are collected in one voltmeter. What mass of copper will be deposited on the cathode of the other? (Cu=64,H=1,Faraday's constant 96500Cmol-1,molar volume =22.4dm³..
(2) A metal of RAM 27 was deposited by electrolysis. If 0.176g of the metal was deposited on the cathode when a current of 0.15A flows for 7/2 hours, what's the charge on the cathode of this metal? (Faraday's constant =96500Cmol-1)...
