Moreover, the increasing in size of the molecules and ions leads to the decreasing in attraction of the water molecules. Group 1: Alkali Metals and Carbonates (X 2 CO 3) is the reaction between Li, Na, K, Rb and Cs with CO 3. Group-1 carbonates are soluble in water except for Li 2 CO 3 As we move down group 1 and group 2, the thermal stability of nitrate increases. If a thick white precipitate forms which does not dissolve when dilute HCl is added to it then there are either ions of sulphate or hydrogensulphate present. & Test it!
