    Can you help me answer the following question?

    Calculate the pH at the equivalence point in each of the following titrations;
    (i) CH3COOH + NaOH pKa = 4.74 for CH3COOH
    (ii) NH3 + HCL pKb = 4.74 for NH3

    Assume that in each case each solution titrated contained initially 0.001 moldm^-3 of reagent.

    The only similar calculations I've done have been where you are given the Ka value (which I know you can calculate form pKa) and the volume and concentration of the acid and base. I don't know how to obtain pH with so little information.

    I'd appreciate any help you can give me, thank you in advance.

    PS
    I know that the answers are 8.22 for (i) and 5.78 for (ii) if that helps.
