Answer 2

Increasing solubility :

Explanation:

• Solubility is the ability of a solid, liquid, or gaseous chemical substance to dissolve in a solvent and form a solution.

• The solubility of a substance is depends on the solvent used, as well as temperature and pressure.

• The solubility of NaCl at constant temperature & pressure in water is 35 g per 100 mL.

• The solubility of CuI at constant temperature & pressure is 0.000042 g per 100 mL.

• The solubility of Sr3(PO4)2 at constant temperature & pressure is 1.0×$10^{-31$ g per 100mL.

• The solubility of HgBr2 at constant temperature & pressure is 0.61 g per 100 mL.

• From the above data, we can arrange the compound in increasing solubility as :

       Sr3(PO4)2 < CuI < HgBr2  < NaCl
