The common-ion effect and buffer systems A buffer is a mixed solution of a weak acid or base, combined with its conjugate. Note that this can be understood essentially as a common-ion problem: The conjugate is a common ion added to an equilibrium system of a weak acid or base. The addition of the conjugate shifts the equilibrium of the system to relieve the stress of the added concentration of the common ion. In a solution consisting of a weak...

A weak acid (HA) has a pKa = 2.77. Assuming the volumes are additive, calculate the volume (in mL) of 0.500 M HA, O.500 M NaA, and water required to make 250.00 mL of a buffer with a total concentration of 0.400 M and (a) pH= 2.77; (b) pH= 2.25; (c) pH= 3.00. Calculate the buffer strengths of the thee buffers in the problem. Please show work on buffer strength calculation.
