Derive the a expressions for the triprotic acid H3ASO3, also written as As(OH)3), arsenious acid. The pK values for this acid are 9.29, 12.04, and 13.34. Evaluate and plot the values of o, 01, 02, and a3 at half-unit pH values over the range 8-13 and plot the results. Note: do not attempt to do this problem by hand calculations; use a spreadsheet program to insert the a; formulas and to plot the results.
