Hardness of Water Essay

The severelyness of wet supply system supply was determined use the methods of titration, conductivity, and pH analysis. The look upon and incredulity of CaCO3 is 13436.0 ppm. An error that could spend a penny potentially happened could be that the equivalence menstruation was not correctly established causing inaccurate data.BACKGROUND 1In hard water there is a high amount of mineral content indicate in the water.Most of the mineral content that is present in water are Ca2+ and Mg2+ ions. Even though hard water does affect a persons health, hard water can still have harmful effects in an industrial environment, appliances in a planetary house setting, and certain cleaning task. 2For example, when hard water repeatedly goes through pipes, the water causes deposits that eventually build up and clog the pipes. When cleaning dishes the presence of hard water can be detected when a layer of charge is present on the dishes.Soap becomes less effective when hard water is present because the soap will bond with the minerals in the water. PROCEDURE Hirko, R. interpersonal chemistry 112L General Chemistry I Laboratory, Seventh Edition bluedoor Minnetonka, MN, 2013 RESULTS remit 1. Ca2+/Mg2+ in tap water via EDTA titration. Table 1 results were determined by pH analysis and EDTA titration. The moles of EDTA was found by using the EDTA stringency of 0.025 mol/L. Table 2. Conductivity probe calibration Figure 1.

Freshwatersystems, n.d. Web. 12 Oct. 2013. DISCUSSION The mean and uncertainty for CaCO3 for tap water was determined to be 13436.0 ppm. For the EDTA titration trial 2 and trial 3 had the same results of 125 ppm compared to trial 1, which had a higher(prenominal) ppm of 150. The readings for thehardness of water for the 3 different trials are not convertible and dif fer in value. The CaCO3 value for the volumetric data was 134 ppm, the value for NaCl was clxxx ppm, and the value for 442 was 248 ppm.The hardness of water can never be authoritative because the water in Brookings may be different than the water in Sioux Falls. If it was possible to always have the same amount of mineral concentration then it would be definitive. Errors that could that potentially happened is when titrating it was difficult to tell when the equivalence point actually occurred, causing more or less amount of EDTA to present. not knowing the when the equivalence point actually occurred would cause inaccurate values because the volume would be incorrect. Another error could be that the magnetic stirrer was spinning fast enough to mix the solution properly.This would cause extravagance EDTA to be present causing inaccurate results. An improvement for this lab would be test different hard water sources rather than just virtuoso faucet.
