EDTA titration
« on: November 07, 2009, 09:17:28 PM »
The concentration of standardized EDTA is determined by titration of 25.0 mL of 0.100 M CaCl2 solution by 35.0 mL EDTA.

Scandium is determined by titration of Sc3+ with the standard EDTA.
Sc3+ + H2Y2− → ScY− + 2H+

A 1.00-g sample is titrated by 35.0 mL EDTA.
Calculate the percent Sc2O3 in the sample.
