The ionization constant of chloroacetic acid is 1.35 × 10^–3. What will be the pH of 0.1M acid and its 0.1M sodium salt solution?

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.

p H

of a simple sodium acetate buffer is given by

p H = p K_{a} + log \frac{[S a l t]}{[A c i d]}

K_{a}

= 1.8 \times 10^{- 5}

If [Salt]=[Acid]

= 0.1 M
