Chemistry Class 11 NCERT Solutions Chapter 7 Equilibrium Part 14

Q: 44. The ionization constant of phenol is . What is the concentration of phenolate ion in 0.05 M solution of phenol? What will be its degree of ionization if the solution is also 0.01M in sodium phenolate?

Structure of Phenol-Phenolate Equilibrium.

Structure of Phenol-Phenolate Equilibrium


Ionization of phenol

As the value of the ionization constant is very less, x will be very small. Thus, we can ignore x in the denominator


Now, let α be the degree of ionization of phenol in the presence of 0.01 M
