A ferric phosphate solution is prepared by adding 2.4 g of ferric phosphate to a volumetric flask and bringing the final volume to 1 L by adding water having a phosphate concentration of 1 mg *L^-1. What is the concentration of soluble iron in this solution? (Assume temp of solution is 25 degs celc)
The data obtained are 20.36, 19.98, 20.26, 20.18, 19.72, 19.86% Cl. (a) what is the standard deviation of this data. (b) find the 90% and 99% confidence intervals for the percentage of chloride in the sample. Must show work for credit
