Standard Addition

1. Single Point Method

A water sample was analyzed by ion chromatography to determine the concentration of Mg2+ and gave a peak area of 0.064 mS-min. Then 5.0 mL of water sample was spiked with 1.00 mL of 20.00 ppm Mg2+ and diluted to the mark with deionized water in a 10.00 mL volumetric flask. The resulting solution gave a peak area of 0.095 mS-min. What is the concentration of Mg2+ in the water sample?
