    contribution to water hardness‚ by convention hardness is reported as mg 〖CaCo〗_3/L of solution. Water with a hardness value less than 60 ppm is considered “soft” water‚ while water ≥ 200 ppm 〖CaCo〗_3/L is labeled as “hard”. How: Ethylenediamminetetraacetic Acid (EDTA) is a complex versatile chelating agent. A chelating agent is a substance whose atoms can form several bonds (ligands) to a single metal ion. Chelating agents are multi-dentate ligands. Multidentate ligands are many clawed‚ holding onto the metal

    Abstract In this experiment‚ the Ksp for calcium sulfate dihydrate‚ CaSO4·2H2O‚ by titrating 4 times a calcium sulfate dihydrate solution with diprotic EDTA‚ H2(EDTA)2-. For each trial we found the Ksp by means of molarities and activities. The results for the Ksp using only molarities was very different than the Ksp using activities. The average Ksp using molarity only was 2.26 x 10-4 and the average Ksp using activity turned out to be 2.31 x 10-5. The actual Ksp however‚ is 3.14 x 10-5. A percent

    soil property. These two tests are the falling head permeability test and the constant head permeability test. Which test is used depends upon the type of soil to be tested. For soils of high permeability (sands and gravels) a constant head test is used. For soils of intermediate to low permeability‚ a falling head test is used. As we were testing sand we used a constant head permeability test. By carrying out the constant head permeability test we can determine the coefficients of permeability of
