Experiment #3 Discussion The purpose of the experiment was to find what is in tap water, ocean water, and deionized water. And how much of whatever is in the water there is. Also to learn terms relating to solutions. Part I By boiling off the water in tap/ocean water we find the amount and concentration of dissolved solids in tap/ocean water. The test was conducted by cleaning and drying a beaker, filling it with 75.0mL, gently boiling away the water, and doing calculations to find the concentration and percent of solids in tap/ocean water. The outcome for my tap water was 1040ppm, 0.105%. The average concentration for tap water is 549.5ppm, giving .055%. The average concentration for ocean water is 48539.8ppm, and 4.52%. Salt water has a lot more dissolved solids than tap water. Part II By testing for many different chemicals we can determine what is in tap water. The test was conducted by boiling off some water in a tap water solution to make the concentration of dissolved solids higher. Then 1-2mL of tap water was placed into 6
