If you need to prepare 250.0 mL of a pH 5.00 buffer that has a total buffer concentration of acetic acid + sodium acetate of 0.050M, how many moles of each will you need to prepare the solution? Given solutions of acetic acid and sodium acetate with concentrations of 0.10M and pKa = 4.76; describe how to prepare this buffer.

  • Chemistry - ,

    For the first part, you have two equations.
    base + acid = 0.05
    5.00 = 4.76 + log (base(/(acid)
    Solve those two simultaneously for acid and base.

    Post again if you have trouble with the second part.

  • Chemistry - ,

    this was no help. at. all.
