electrolysis of HCl?

溶左係水就可以,
有ions就可以做electrolysis,
因為HCl溶左係水會dissolve and then ionize,
會give out H+ 同Cl-,
做electrolysis會用電流ge方向黎產生正[anode]負[cathode]2極,
吸引正/負ions去cathode/anode

cathode: H+ [H+ discharged--->form H2]
anode: Cl- , OH- [DIL: OH- discharged--->form O2][CONC: Cl- discharged--->form Cl2]
