The pH of 0.1M solution of cyanic acid (HCNO) is 2.34. Calculate the ionization constant of the acid and its degree of ionization in the solution.

Options

  1. AKa = 2.0 × 10 -4 , α = 0.045
  2. BKa = 1.5 × 10 -3 , α = 0.015
  3. CKa = 1.2 × 10 -3 , α = 0.016
  4. DKa = 1.3 × 10 -4 , α = 0.018

Correct answer

A. Ka = 2.0 × 10 -4 , α = 0.045

Step-by-step solution

Correct Option is : (A) Ka = 2.0 × 10 -4 , α = 0.045
