Experiment 3 Analysis of water The purpose of this experiment is to use chemical and physical tests to determine the concentration and types of dissolved solids in tap water and ocean water. The tests performed in this experiment will determine the amount of dissolved solids, ions and other contaminants in tap water and ocean water. Nitrates in drinking water is a big concern for people and is a result of agricultural runoff which is fed into rivers. Nitrates can ultimately cause respiratory failure, primarily in newborns. The objective is to recognize and use the proper terminology common in solutions and to provide an introduction to solubility rules for ionic compounds in water. The first experiment performed was the analysis of ocean water for the purpose of determining the total amount of solids and dissolved solids in units of ppm. This test starts with a 400-mL beaker that is washed and dried completely in an oven. Once the beaker is dry (20 minutes) and at room temperature, it is weighed with boiling stones. After the weight is determined, approximately 75.0-mL of tap water is poured into the beaker and is re-weighed. A hot plate or Bunsen burner is
