Question

If the concentration of potassium chloride is low during electrolysis, why is oxygen produced at the anode instead of chlorine?

I don't understand where the oxygen is from, what the solution and electrolyte are. Any help is greatly appreciated

Answer 1

I think the question just answered it self, since it says that the concentration of `KCl` is low..

Explanation:

Hence most of the chlorine if not all would have been used up in the reaction..

`C = m/v`

And where the oxygen is coming from, perhaps water is used as a solvent or it is contained in the solution..
