Complexometric Titration
« on: January 01, 2019, 07:15:59 PM »

The Zn in a 0.7162g sample of powder was titrated with 21.27mL of 0.01645M EDTA. Calculate the %Zn in this sample.

---------------

1/1 Ratio

0.01645 M x 0.02127 L = 0.000349891 mol
Mass of Zn: 0.000349891 mol x 65.39 g = 0.02287 g
% in sample: 0.02287 g / 0.7162 g (sample weight) = 3.195%
