NEET Chemistry Solubility Product MCQ Question
Which of the following statements about the solubility product (K_sp) is correct?
K_sp represents the equilibrium constant for a sparingly soluble ionic compound.
K_sp is always equal to the concentration of the solid in a saturated solution.
The solubility of a salt increases in a solution where a common ion is present.
K_sp varies with temperature but does not depend on the concentrations of the ions in solution.
Correct Answer
Detailed Explanation
K_sp is defined as the equilibrium constant for the dissolution of a sparingly soluble ionic compound, as indicated in the description of the equilibrium between the solid and its ions in the saturated solution. Option B is incorrect because the concentration of the solid does not appear in the K_sp expression. Option C is incorrect as the presence of a common ion typically decreases solubility. Option D is also incorrect since K_sp does depend on the concentrations of ions in solution.
