Tartaric acid is found in many fruits including grapes. Tartaric acid is partly responsible for the dry texture of certain wines. Tartaric acid, H2C4H4O6, is a diprotic acid with the following Ka values Ka1 = 1.00 x 10-3 Ka2 = 4.60 x 10-5 a. Write the equation for the 1st ionization of tartaric acid. b. Write the equation for the 2nd ionization of tartaric acid. c. Write the Ka expression for the 1st ionization. d. Write the Ka expression for the 2nd ionization. e. What is the equilibrium concentrations of the reactants and products from the 1st ionization of a 0.250M solution of tartaric acid? f. What is the equilibrium concentrations of the reactants and products from the 2nd ionization? g. What is the total [H3O+] and the overall pH of the solution of tartaric acid?
