Answer to Question #191260 in General Chemistry for Kam

Question

Which of the following salts would be more soluble in acidic solution than in neutral water?

PbI2

Li3PO4

AgCl 

SrSO4

CuBr

Answer 1

If we made to react any of the salt with acid than the acid donates its H$^+$ ion,and the salt used to react with that H$^+$ ion.

According to the above options available we find that only for CuBr adding H$^+$ forms HBr and that is a weak acid; therefore, CuBr is more soluble in acid than in water.
