Buffer capacity = resistance to pH change from addition of acid or base! •depends on concentration of buffer species---higher concentration more buffer capacity!---a 0.10 M Tris buffer would have more buffer capacity than a 0.01 M Tris buffer! WebA solution with more weak acid, [HA], has a higher buffer capacity for addition of strong base. So although the pH of a buffer is determined by only the ratio [A - ]/ [HA], the …
WebBuffer capacity depends on the concentrations of the species in the solution; the more concentrated the buffer mixture, the higher the buffer capacity.
