A solution of volume 25.00 mL containing 0.0311 M Na2C2O4 was titrated with 0.0257 M La(ClO4)3 to precipitate lanthanum oxalate:
2 La3+ + 3 C2O42- La2(C2O4)3(s)
(e) Plot the titration curve for this titration using Excel or other spreadsheet software
(f) Plot the titration curve for the same titration if the concentration of the titrant is increased to 0.0500 M. What effect does this have on the shape of the titration curve?
(g) Another analytical chemist performed the titration of the same oxalate sample using calcium to precipitate calcium oxalate. Is this a better approach to this analysis? Why or why not?
