hanson6922 Posted April 5, 2012 Share Posted April 5, 2012 Limestone is a form of calcuim carbonate which is slightley soluble in water producing dissolved calcuim and bicarbonate ions, would you expect the water to be hard or soft?What would you expect to occur to the concentration of calcuim, magnesium and sodiaum ions in hard water when water is artificailly softened by passing through an ion- exchange filter? any help would be appreciated.

The second question itself is a hint to the first one. Link to comment Share on other sites More sharing options...
