Question

Write the product obtained at anode on electrolysis of concentrated sulphate sulphuric acid and using platinum electrodes.
`H_(2)SO_(4)overset((aq))rarr 2H_((aq))^(+)+SO_(4)^(2-)(aq)`

Answer 1

At cathode : `2H^(+)+2e^(-) to H_(2)(g)`
At anode : `2SO_(4)^(2-)(aq) to (S_(2)O_(8))^(2)+2e^(-)`
