- Where do sodium ions go in a pool?
It is killing me trying to understand why sodium ions don't continuously build up in swimming pools.
You add NaCl to a pool. It is electrolysed to H2 and Cl2 leaving Na+ and OH-.
I get OH- builds up over time, and needs to be neutralised by HCl to make NaCl again and water. This would balance out charges, but you quite often put more NaCl in the pool.
I would guess the Cl2 leaves as a gas or perhaps as HCl gas over time, but there must be some mechanism for how Na+ leaves. Can someone help me?
