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?


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
