Predict the products of electrolysis of a solution of `H_(2)SO_(4)` using platinum electrodes. |
|
Answer» (a) By the elctrolysis of dilute solution of `H_(2)SO_(4)` For answer, consult 18(N.C.E.R.T. Exercise). (b) By the electrolysis of strong `H_(2)SO_(4)` `H_(2)SO_(4) to underset((Cathode))(2H^(+))+underset((Anode))(SO_(4)^(2-))` `"At cathode" : " " 2H^(+)+2e^(-) to 2HorH_(2)` `"At anode" " " 2SO_(4)^(2-) to (S_(2)O_(8))^(2-)+2e^(-)` `(SO_(4)^(2-)` ions will take up `H^(+)` ions from the solution to from `H_(2)S_(2)O_(8)`which is peroxydisulphuric acid. |
