100 mL of 1.0 M formic acid (HCOOH) is titrated with 1.0 M sodium hydroxide (NaOh).

The Approximate pKa is 4

At the pKa, what fraction of the carboxyl group will have been converted to COO-?

    Do you mean at a pH = pKa, what is the fraction?
    pH = pKa + log(base)/(acid)
    4 = 4 + log (base)/(acid)
    (base)/(acid) = 1
    So 50% has been converted.
