Chemistry-Chemical Equilibrium
NEET Chemistry Chemical Equilibrium MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Which of the following statements about weak acid-ionization equilibrium is correct?
A
The ionization constant of a weak acid is always greater than that of a strong acid.
B
Weak acids partially ionize in solution, establishing an equilibrium between the acid and its ions.
C
At equilibrium, the concentration of the undissociated weak acid is equal to the concentration of its ions.
D
The degree of ionization of a weak acid increases with increasing initial concentration.
Correct Answer
Option B
Detailed Explanation
Weak acids partially ionize, meaning they do not completely dissociate in solution. This leads to an equilibrium established between the undissociated acid and its ions, as indicated in the NCERT context.
