1.

In the electrolysis of water, one faraday of electrical energy would evolveA. one mole of oxygenB. one g atom of oxygenC. 8 g of oxygenD. 22.4 litres of oxygen

Answer» Correct Answer - C
Hydrolysis of water: `2H_(2)Oto4H^(+)+4e^(-)+O_(2)`
4 F charge will produce=1 mole `O_(2)=32gm" "O_(2)`
1 F faraday will produce`=(32)/(4)g` gm `O_(2)`.
