Challenge Problem:
(a) Plot logarithmic concentration diagrams for 0.1000 M solutions of each of the acids in Problem above.
(b) For phthalic acid, find the concentrations of all species at pH 4.8.
(c) For tartaric acid, find the concentrations of all species at pH 4.3.
(d) From the log concentration diagram, find the pH of a 0.1000 M solution of phthalic acid, H2P. Find the pH of a 0.100 M solution of HP2.
(e) Discuss how you might modify the log concentration diagram for phthalic acid so that it shows the pH in terms of the hydrogen ion activity, aH+, instead of the hydrogen ion concentration (pH = -log aH+. instead of pH = 2log cH+). Be specific in your discussion and show what the difficulties might be.
Problem Calculate alpha values for the following diprotic acids every 0.5 pH units from pH 0.0 to 10.0. Plot the distribution diagram for each of the acids and label the curve for each species.
(a) phthalic acid.
(b) succinic acid.
(c) tartaric acid.
