  • During the electrolysis of potassium chloride solution, the electrolyte becomes more and more alkaline. Explain why this happens.

Please help, thanx

Well, the more acidic a substance is, the more hydrogen it contains... the more alkaline a substance is, the less hydrogen it contains. So I think it has something to do with the fact that that the electrolyte is losing hydrogen atoms, possibly because they turn to +1 ions and react with the potassium which collects at the bottom of the container, leaving the electrolyte more alkaline than before.
