✔ 最佳答案
The ionic equation is as below:4OH- (aq) → O2 (g) + 2H2O (l) + 4e-
This is a process is electrolysis of water. In the anode (positive electrode), hydroxide ions are discharged to oxygen gas and water, releasing 4 electrons.

2H2O → H3O+ + OH-
水入面有 d mobile ions
佢地係 hydronium 同埋 hydroxide
你可以話水 ionize 造左 OH- 出黎既
