Question

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

Answer 1

(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.
