WebQuestion: Lab 6: Determination of Water Hardness by EDTA Titration Introduction: Water hardness is a measurement of the total concentration of Ca2+ and Mg2+ in water, reported in ppm as though it were all CaCO3. The calcium content from the three trials performed were 210.3 ppm, 200.3 ppm, and 200.7 ppm. 2) 200.3 WebWhen the water hardness test strip is dipped in a water sample, a color develops on the strip and the strip is matched to a chart.

Eriochrome Black T will be used as an indicator. Use the test strips when a general range for hardness is sufficient. Note the value of calcium carbonate in the report and compare it to the following scale used by the U.S. Geological Survey: Soft water: 0-60 mg/L; Moderately hard water: 61-120 mg/L; Hard water: 121-180 mg/L; Very hard water: Over 180 mg/L; WebIntroduction In this experiment, water samples from the Nature Preserve located on Binghamton Universitys main campus are collected and brought to the lab to measure its hardness.

Water hardness is a measure of the concentration of all the polyvalent cations dissolved in the water. To optimize these processes, it is sometimes important to monitor calcium and magnesium levels separately, along with total hardness. Since an analysis Classify your Tap Water samples based on The average of these three trials with standard deviation was 203.8 5.66 ppm. s=1 .pdf, No public clipboards found for this slide, Enjoy access to millions of presentations, documents, ebooks, audiobooks, magazines, and more. Dissolve the solids in water and transfer this solution into a clean 1 liter volumetric flask. resin. Recarbonation, or the reintroduction of carbon dioxide, must be performed after softening to lower pH, to remove excess lime and to encourage the precipitation of any remaining calcium carbonate. Hardness can be classified as carbonate and non-carbonate hardness. Click here to review the details.
