I think you are asking about the solubility in water of some ionic compounds.
1.
Calcium oxide (CaO) reacts with water to give calcium hydroxide which is slightly soluble in water.
CaO(s) + H2O(l) → Ca(OH)2(aq)
CaO is classified as soluble or slightly soluble.
2.
Calcium hydroxide is slightly soluble in water.
3.
Calcium carbonate is insoluble in water.
4.
Calcium sulphate is slightly soluble in water.
5.
Calcium chloride is soluble in water.
