Question

Using solubility rules, determine if the following compounds are soluble in water. insoluble soluble A. CuCl2 B. BaSO4

Answer 1

Answer :

(A) $CuCl_2$ : It is soluble in water.

(B) $BaSO_4$ : It is insoluble in water.

Explanation :

Solubility : It is defined as the amount of solute dissolved in a solvent at a given temperature.

According to the solubility rules:

All chlorides are soluble except $Ag^+,Pb^+\text{ and }Hg^{2+}$

All sulfates are soluble except $Ba^{2+},Pb^{2+},Ca^{2+}\text{ and }Sr^{2+}$

From this we conclude that,

(A) $CuCl_2$ : It is soluble in water.

(B) $BaSO_4$ : It is insoluble in water.
