Dissolved Mineral Salts. 1  The principal ions found in water are calcium, magnesium, sodium, bicarbonate, sulfate, chloride and nitrate. A few parts per million of iron or manganese may sometimes be present and there may be traces of potassium salts, whose behavior is very similar to that of sodium salts.
When ionic compounds dissolve in water, the component ions dissociate and move about independently. What ions would be present in solutions K2Cr2O7 (potassium dichromate) and NH4Cl (Ammonium choride)?
