A series of volumetric flasks are being prepared for the analysis of mercury in the drinking water supply using standard addition. To prepare flasks, 10 mL of drinking water and a varying amount of standard are added to each flask, and the flasks are brought to the 25.0 mL mark on the volumetric flask. The concentration of mercury standard solution used was 20.0 micrograms per mL.
Ans. Create a data table as shown below to calculate [Hg] from various standard additions. Plot [Hg] added from standard solutions of various aliquots vs signal, label the axes appropriately. Generate the trendline equation or linear regression equation for the standard graph.
