Problem

A current of 0.5 A is passed through acidulated water for 30 minute. Calculate mass of

\text{H}_2

and

\text{O}_2

evolved. Also calculate the volume of

\text{O}_2

produced at

25^\circ\text{C}

and 760 mm of Hg if the gas is : (a) dry (b) saturated with water vapour (aqueous tension is 23.0 mm at

25^\circ\text{C}
