Question

Which one of the following salts in insoluble in water?

a. CrCl₃
b. AgF
c. PbSO₄
d. Mn(NO₃)₂
e. Cu(ClO4)₂

Answer 1

Out of the salts listed, lead(II) sulfate (PbSO4) is insoluble in water, following the established solubility rules.

Step-by-step explanation:

The question asks which one of the salts listed is insoluble in water. According to solubility rules, most sulfate salts are soluble except for a few exceptions such as barium sulfate (BaSO4), lead sulfate (PbSO4), silver sulfate (Ag2SO4), and strontium sulfate (SrSO4). Given the options provided in the question, PbSO4 (lead(II) sulfate) is the insoluble salt in water.
