Question
Consider the HClO/ClO- conjugate acid/base pair. Consult your text or other source for appropriate acid dissociation constants. The hypochlorite ion is the active ingredient in bleach, NaClO(aq). (a) Explain why this acid/base pair would be a candidate for a buffer with pH = 7.3 (approximate physiological value).Consider the HClO/ClO- conjugate acid/base pair.

Explanation / Answer
The paka of KClO is 7.46
And we know a good buffer has pH = pKa +1 or pKa=1 range where its buffer action is maximum.
therefore the acid with pKa value around 7.3 are the best ones to prepare a buffer of pH = 7.3
Thus HClO/ClO- makes a better candidate for the buffer of pH = 7.3
