1. The problem statement, all variables and given/known data 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. 2. Relevant equations 3. The attempt at a solution when it dissociate, C3H5O3- formed, but i dont know the concentration of H+ and C3H5O3- when it is in equilibrium, so how can i cal. Ka?
