Question

On diluting a buffer solution, its pH.--------​

Answer 1

Answer:

Generally, dilution has NO effect on the pH. Why is this so? If you look at the buffer formula, pH = pKa + lg [salt]/[acid], dilution does not affect the [salt]/[acid] ratio. i.e. they are diluted to the same extent or volume would cancel out.

Answer 2

Answer:

Pka + lg
