  1. Question 1

    Q1. In a comparison of a weak acid and its conjugate base, the relationship between Ka and Kb is defined by which constant fact?

    • A) The product of Ka and Kb equals the ionic product of water
    • B) The sum of Ka and Kb equals 14
    • C) Ka is always greater than Kb for any salt
    • D) They are independent of the temperature of the solution

    Answer: The product of Ka and Kb equals the ionic product of water

    Explanation: The product of Ka and its conjugate base's Kb always equals Kw (10^-14), showing an inverse relationship between their strengths.
