  1. Question 1

    Q1. Under what condition will a precipitate form when two solutions containing ions of a sparingly soluble salt are mixed?

    • A) The ionic product exceeds the solubility product
    • B) The solubility product exceeds the ionic product
    • C) The solution is exactly saturated
    • D) The temperature of the solution is decreased

    Answer: The ionic product exceeds the solubility product

    Explanation: Ionic product (Qi) > Ksp results in precipitation. Option B is wrong because Qi < Ksp means the solution is unsaturated.
