A question from 2011 asked about resin ion exchange however my text book only talks about magnesium and calcium ion exchange. Does anyone know where i could find notes on resin ion exchange?
A resin ion exchange is the same thing as a calcium and magnesium ion exchange (I think: stand to be corrected). But as far as I know you pass it through a resin to remove the calcium and magnesium ions and replace it with sodium
ions for soft water.
