Buffer Capacity
- The effectiveness of a buffer
in maintaining pH depends on
the relative concentrations of
acid and base in the solution
- A buffer solution with a high
concentration of acid and base can
neutralise more added base and acid
than one with low concentrations
- if [weak base] = [weak acid]
in a buffer solution, then
[H3O+] = Ka and pH = pKa
- In any buffer solution, the
pH is close to the pKa of
the weak acid component
when the acid and base
have similar concentrations
- The buffer is
effective in the pH
range of pKa +/= 1
