Question

electrolysis of water whrite down the ionic equation that will take place at the cathode electrode​

Answer 1

In pure water at the negatively charged cathode, a reduction reaction takes place, with electrons (e−) from the cathode being given to hydrogen cations to form hydrogen gas. The half reaction, balanced with acid, is: Reduction at cathode: 2 H+(aq) + 2e− → H2(g)Cathode (reduction): 2 H2O(l) + 2e−
