Question:

Use the equation derived in Problem 11-19.
(a) Prepare a spreadsheet to reproduce the 20-, 50-, and 60-mL points in the EDTA titration of Zn2+ in the presence of NH3 in the example on pages 248-249.
(b) Use your spreadsheet to plot the curve for the titration of 50.00 mL of 5.00 mM Ni2+ by 10.00 mM EDTA at pH 11.00 in the presence of a fixed oxalate concentration of 0.100 M.
