Two students are tasked with determining the milligrams of chloride in a simulated soil sample. Both students extract chloride into aqueous solution and perform triplicate titration with silver nitrate solution and dichlorofluorescein indicator. The students report the following results to their laboratory instructor. If the accepted value is 36.90 mg chloride/g sample, the laboratory instructor infers that student #2's work exhibits student #1.
