Say, for example, that you had prepared a Buffer C, in which you mixed 8.203 g of sodium acetate, NaC2H3O2, with 100.0 mL of 1.0 M acetic acid.
a. What would be the initial pH of Buffer C? HOW???????

  • Chemistry -

    (Acetate ion) = ?
    moles = grams/molar mass
    M = moles/0.1L
    (acetic acid) = 1M

    pH = pKa + log(acetate)/(acetic acid)
    pKa = -logKa

  • Chemistry -

    Yeah i know it now it is the henderson Hasselbach equation
