The pH of such a buffer is established by the relative concentrations of HB and B in the solution. If we
manipulate Equation 4, we can solve for the concentration of H+ ion:
[H] = K₂ X [HB]/[B]
(4a)
This equation is often further modified when working with buffers, by taking the negative logarithm to base
10 of both sides:
pH pK,+ log [B]/[HB]
