NEET Chemistry Chemical Equilibrium MCQ Question
Which of the following statements about weak acids and their conjugate bases is correct?
The strength of a weak acid can be inferred from its ionization constant.
All weak acids have higher pK values than their conjugate bases.
The pH of a solution of a weak acid is always less than 7.
Conjugate bases of weak acids do not affect the pH of their solutions.
Correct Answer
Detailed Explanation
The strength of a weak acid is represented by its ionization constant (K_a), where a higher K_a indicates a stronger acid. This concept is supported by the relationship between the ionization constants of conjugate acid-base pairs as outlined in the NCERT content.
