A buffer capacity is a measure of a buffer solution's resistance to changes in pH as strong acid or base is added. Suppose that you have 145ml of a buffer that is 0.220M in both benzoic acid (C6H5COOH) and it's conjugate base (C6H5COO-). Calculate the maximum volume of 0.220M HCL that can be added to the buffer before it's buffering capacity is lost.

  • Buffers are solutions designed to resist changes in pH from the addition of small amounts of acids or bases

    Buffers are solutions designed to resist changes in pH from the addition of small amounts of acids or bases. Buffers are comprised of a solution of a weak acid with its conjugate base. When an outside base is added to the buffer, the weak acid in the buffer neutralizes the hydroxide ion of the base, thus retarding its ability to raise the solution's pH. When an outside acid is added to the buffer, the conjugate base of the buffer neutralizes...
