Experiment #11 Determination of Water Hardness
Experiment #11 Determination of Water HardnessElizabeth Stassenko1/21/16Purpose: ● To become familiar with the concept of water hardness● To practice a titration technique using a titrator ● To determine the hardness of the local water supply [pic 1] [pic 2][pic 3][pic 4][pic 5][pic 6][pic 7][pic 8]Data and Observations: [pic 9]Questions A. Based on the analysis of your local water, would you classify its hardness as soft, moderate, hard, or very hard? Explain your answer. I would describe my local water as soft because 3 ppm falls within the soft classification (0-60 ppm). B. Approximately how much calcium would you ingest by drinking eight 8-oz glasses of your local water? Hint: 1oz (fluid ounce) = 29.57 mL. I would ingest approximately 25.03 mg of calcium by drinking eight 8 oz glasses of my local water. C. Assume an average minimum daily requirement for calcium is 1,150 mg. Calculate what percentage of your daily requirements could be met by drinking 1.0 L of your local water.
