A current of 0.5 A is passed through acidulated water for 30 minute. Calculate weight of H_(2) and O_(2) evolved. Also calculate the volume of O_(2) produced at 25^(@)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^(@)C).

Answer»


Answer :`H_(2) = 9.33 XX 10^(-3)G`,
`O_(2) = 7.46 xx 10^(-2)g`,
(a) `5.7 xx 10^(-2)` litre, (B) `5.88 xx 10^(-2)` litre;
