To deposit one litre of hydrogen at `22.4` atmosphere from acidulaled water, the quantity of electricity that must pass through is

What volume of hydrogen gas measured at 273 K at 0.5 atmospheric pressure will be obtained when 0.1 faraday of electricity is passed through acidulated water ?

To deposit one gm equivalent of an element at an electrode. The quantity of electricity needed is

Electric current is passsed through acidulated water.

On passing a current through a KCl solution, 19.5g of potassium is deposited. If the same quantity of electricity is passed through a solution of aluminium chloride, the amount of aluminium deposited is

When a quantity of electricity is passed through CuSO_(4) solution, 0.16 g of copper gets deposited. If the same quantity of electricity is passed through acidulated water, then the volume of H_(2) liberated at STP will be : (given atomic weight of Cu=64)
