water hardness testing procedure
This test is important in many industries that use water for various applications such .
One of the factors that establishes the quality of a water supply is its degree of hardness. The hardness of water is defined in terms of its content of calcium and magnesium ions. The hardness of good quality water should not exceed 250 mg/L measured as calcium carbonate equivalents. Waters softer than 30 to 50 mg/L may be corrosive to piping depending on pH, alkalinity and dissolved oxygen. .The hardness of high-quality water should not exceed 270 mg/l (15.5 grains per gallon) measured as calcium carbonate. Water softer than 30 to 50 mg/l may be corrosive to piping, depending on pH, alkalinity and dissolved oxygen. Water softeners will correct hard water of more than 270 mg/l.
Lab 1 Prepare and standardize your calcium carbonate and EDTA solutions. Lab 2 Analyze your water samples for total hardness and for calcium. Lab 3 Finish your analyses.

Hard water does not mix well with soaps. Because of this, you can test for the hardness of water by looking at the amount of bubbles produced when you mix water and soap.This lab is concerned with hardness, which is the amount of divalent metallic cations in the water.The primary causes of hardness are calcium (Ca +2) and magnesium (Mg +2) ions, but other metals such as strontium, ferrous iron, manganous, aluminum, and ferric iron can also contribute to hardness.Of these, ferric iron and aluminum ions tend to have little effect on .

Dyal Water Treatment Plant (WTP) and our NELAC (National Environmental Laboratory Accreditation conference) certified laboratory perform chemical analysis and bacteriological . To avoid the adverse effects of hard water, the calcium and magnesium mineral content in the water should be below 60 mg/L. The USGS standards for water hardness levels are as follows: Soft water: 0 to 60 mg/L; Moderately hard water: 61 to 120 mg/L; Hard water: 121 to 180 mg/L; Very hard water: Any level above 180 mg/L

Most utilities report their water hardness numbers in milligrams per Liter (mg/L) as calcium carbonate. 3. Use a High-Quality Hard Water Test Kit. A home water test kit is the simplest (and probably the best) way to check your water for hardness minerals. A regular kit usually includes water test strips and a color chart.The outcome of this hypothesis is confirmed by the data in the calculations section of this lab report. This lab experiment demonstrated the successful implementation of complexometric titration to test the “hardness” of tap water. Possible sources of errors in this lab may have resulted from two known systematic errors and random errors.
In scientific terms, water hardness is generally the amount of dissolved calcium and magnesium in water. But in layman's terms, you may notice water hardness when your hands still feel slimy after washing with soap and water, or when your drinking glasses at home become less than crystal clear.
