Homework Statement
when 10 cm3 of a monoprotic acid C3H6O3, with concentration of 7.2g/dm3, was titrated against against 0.05M NaCl, the equivalence point reached when 15.75cm3 (ph8) of NaOH was used.
Calculate the acid dissociation constant Ka for C3H6O3.
Homework Equations
The Attempt at a Solution
[/B]when it dissociate, C3H5O3- formed, but i don't know the concentration of H+ and C3H5O3- when it is in equilibrium, so how can i cal. Ka?
