Consider the titration of 50.0 mL of 0.0110 M Y^3+ (y=yttrium) with 0.0220 M EDTA at pH 5.00. Calculate pY^3+ at the following volumes of added EDTA and sketch the titration curve: (a) 0mL (b) 10.0 mL (c) 25 mL (d) 30.0 mL.© BrainMass Inc. brainmass.com June 4, 2020, 4:30 am ad1c9bdddf
See the attached file.
So I'm showing the calculations for the required volumes. If you plot this, you don't get a smooth curve (shown on page 1 in excel file). Instead if you add a few more points, you can ...
A titration curve for Y3+-EDTA is plotted after calculating values.
