Question

A solution is prepared by adding 500 ml of 0.3 m naclo to 500 ml of 0.4 m hclo. what is the ph of this solution?

Answer 1

Answer;

b. The pH will be less than the pKa of hypochlorous acid.

Explanation;

pH = pKa + log(ClO-/HClO)

pH = pKa + log(0.15/0.20)

pH = pKa - 0.125

Thus;

pH will be less than the pKa of HCLO
