Cyanic acid, HOCN, is a weak acid with a Ka value of 3.5 10-04 at 25C.

Question:

Cyanic acid, HOCN, is a weak acid with a Ka value of 3.5 × 10-04 at 25°C. In a 0.293 M solution of the acid, the degree of ionization is 3.5 × 10-02. Calculate the degree of ionization in a 0.293 M solution to which sufficient HCl is added to make it 4.19 × 10-2 M HCl in the given volume.
