(a) Calculate pCu+ for the titration of 10.00 mL of 0.05000 M of I- with 0.02500 M Cu+ standard solution when 4.500 mL, 20.00 mL and 21.40 mL of titrant have been added. Plot the titration curve for this titration using Excel or other spreadsheet software.
(b) Calculate pCu+ for the titration of 10.00 mL of 0.05000 M of Cl- with 0.02500 M Cu+ standard solution when 4.500 mL, 20.00 mL and 21.40 mL of titrant have been added.
