Tartaric acid is a weak diprotic acid with K_1 = 1 xx 10^(-3)and K_2 = 4.6 xx 10^(-5) .(a) Letting the symbol H_2Arepresent tartaric acid, write the chemical equationsthat represent K_1 and K_2. Write the chemical equation that represents K_1 xx K_2.(b) Qualitatively describe the relative concentrations of H_2A , HA^(-) , A^(2-)and H_3O^+in a solution that is about 0.5 M in tartaric acid.(c) Calculate the pH of a 0.025 M tartaric acid solution and the equilibrium concentration of H_2A(d) What is the A^(2-) concentration? |
