Data Collection Different data tables are prepared in order to establish references used to determine which source contained the most nitrate. One data table describes the nitrate anion concentrations and the source. A second data table indicates each solution and its concentration in molarity, molality, and ppm. A third data table indicates the solution, its concentration, and color change of the test strip. From the comparison of these three data tables, the concretions of nitrate in unknown solutions is determined; therefore, the source of the nitrate poisoning is identified....
