Joseph Marcus Chem 1AL Experiment 3 Discussion Goal: The main goal of this experiment was to be able to use chemical and physical tests to find out concentrations and types of solids that dissolved in tap, ocean, and deionzed water. Method: Evaporating all the water and weighing the residue left in the beaker is done in order to find the concentration of dissolved solids in parts per million (mg solute/ liters solution). For part 2, we tested for several ions, including nitrate, calcium, magnesium, chloride, sulfate, and lead by adding solution that would cause a reaction that we could see the results of and test for the presence of each of these substances. Results There was 639.2209 concentration in parts per million of solids in the water. The percent solid of the water was .0639%. Balanced Equations: See lab report. Experiment First the class was split into two separate groups to analyze ocean and tap water. The class heated beakers in an oven after cleaning them with deionized water and then
