In a titration 25.1ml of a monoprotic weak acid is neutralized with 25.1 ml of .502M NaOH(aq).

Calculate the Ratio of [A-] to [HA] after 12.55 of the .502 M NaOH has been added to the initial amount of HA.

Anyone have any idea what's going on. I got as far as to find the mol's of NaOH which is .0063001 with 12.55mL at a concentration of .502
