A) exceeds the solubility product
B) is less than the solubility product
C) is negligible
D) is equal to the solubility products
Correct Answer: A
Solution :
The precipitation takes place only when the product of concentrations of ions exceeds the solubility product. While if the product of concentrations of ion is less than solubility product, it will dissolve. \[AB{{A}^{+}}+{{B}^{-}}\] If\[[{{A}^{+}}][{{B}^{-}}]>{{K}_{sp}};\]precipitation take place. If\[[{{A}^{+}}][{{B}^{+}}]<{{K}_{sp}};\] substance will dissolve.
