When acidulatd water (di. H_(2)SO_(4) solution) is electrolysed, will the pH ofthe solution be affected? Justify your answer. |
|
Answer» Solution :PH of the solution will not be affected as `[H^(+)]` will remain the same. This is because the amount of `H^(+)` ions reduced is compensated by the `H^(+)` ions produced by oxidation of `H_(2)O`. At cathode: `2H^(+)+2e^(-)toH_(2),` At ANODE: `H_(2)Oto(1)/(2)O_(2)+2H^(+)+2e^(-)`. |
