State the ph of the solution at equivalence

Reference no: EM13174134

A titration curve showed that the equivalence point of a particular acid was achieved when 18.6 mL of 0.135 M NaOH were added to it. The pH of the solution at equivalence was 8.4. At 9.3 mL the pH was 5.3. What is the Ka for this acid? Please show all the work
