Solubility data for selected salts is given together with their solubilty curves graphical representation and how to do simple solubility graph reading and mass of salt crystallising calculations. Dezhi Qi, in Hydrometallurgy of Rare Earths, 2018. Group 2 elements having more polarising power form covalent bonds, they tend to exist in aqueous solution only rather than solid.Thus C a (H C O 3 ) 2 exist in aqueous solution only. allowed volume is 3 ml) with shaking. Water Solubility Add approximately 6 drops of water to the test tube containing your unknown. Barium hydroxide is soluble enough to be able to produce a solution with a concentration of around 0.1 mol dm-3 at room temperature.
