Read the Solubility Rules and answer the Question you see in the pic: Solubility Rules
Compounds containing group 1 alkali metals or ammonium (NH4+) are soluble.

Nitrates (NO3−), chlorates (ClO3−), perchlorates (ClO4−), and acetates (C2H3O2−) are soluble.

Chlorides (Cl−), bromides (Br−), and iodides (I−) are soluble, except for compounds containing silver (Ag+), mercury(I) (Hg22+), and lead (Pb2+).

Sulfates (SO42−) are soluble, except for compounds containing calcium (Ca2+), strontium (Sr2+), barium (Ba2+), and lead (Pb2+).

Hydroxides (OH−), carbonates (CO32−), and phosphates (PO43−) are insoluble, except for compounds containing group 1 alkali metals and ammonium (NH4+).

Sulfides (S2−) are insoluble, except for compounds containing group 1 alkali metals, ammonium (NH4+), magnesium (Mg2+), calcium (Ca2+), strontium (Sr2+), and barium (Ba2+).
