The result is used to calculate the permanent hardness sheriff essay of the water sample. Effects on Human There does not appear to be any convincing evidence that water hardness causes adverse health effects in humans. A lab report is a record of the activities, processes, and observation during and after an experiment. Objectives: Â Use a complexometricÂ titrationÂ to determine the total concentration ofÂ calcium and magnesiumÂ ions in a water sample.
Suggest two other metal ions that could be present in the water. Typical diets provide about 1000 mg of calcium per day and 200â400 mg of magnesium per day. We can then conclude that the bottled Viva mineral water is quite harder than they claim it. Conclusion Determination of Hardness of Water Hard water is due to metal ions(minerals) that are dissolved in the ground water.
