NEET Chemistry Chemical Equilibrium MCQ Question
Which of the following statements about ionization constants and pH is correct?
The ionization constant K_a is directly proportional to the concentration of hydrogen ions in a solution.
A weak acid will have a higher pH than a strong acid at the same concentration.
The pK_b value increases as the strength of the base decreases.
Ionization refers to the separation of existing ions in a solid solute.
Correct Answer
Detailed Explanation
The pK_b value indeed increases as the strength of the base decreases, as indicated by the relation pK_b = -log(K_b). This aligns with the context about bases and their ionization constants in weak bases.
