Question

What happens to the ph if 5.00 ml of this buffer is diluted with water to a total volume of 500 ml?

Answer 1

PH of a buffer solution does not change on dilution.

Buffer solution is combination of salt of weak acid/base.

For example, pH of salt of weak acid strong base is:

pH= pka + [acid][salt] → (concentration ratio)

On dilution, ratio doesn't change. therefore, the pH of the buffer solution does not change.

Diluting a buffer solution would decrease its buffer capacity. we can easily notice that the change on the pH is more important when the concentrations of the acid and conjugate base are diluted.
