    Water Technology Hardness of Water: Natural waters containing large quantities of dissolved salts of Calcium (Ca) & Magnesium (Mg) is called hard water. It is a characteristic of preventing lather formation of water with soap. Ca2+ & Mg2+ ions react with soaps which are salts of fatty acids (stearic or palmitic acid) to give insoluble scums or precipitates of calcium or magnesium stearate or palmitate. 2C17H35COO- + Ca2+ → (C17H35COO)2 Ca (scum) 2C17H35COO- + Mg2+ → (C17H35COO)2

    Chemistry Honors Which Type of Water is the Hardest? Hardness is the quality in water that is imparted by the presence of dissolved salts‚ especially calcium and magnesium. Hardness refers to how many mineral particles there are in water. The harder the water is‚ higher the contents of minerals. A geologist is a person who specialized in geologic research and study; a hydrologist is a geologist that studies the circulation‚ distribution‚ and properties of the waters of the earth and its atmosphere

    Experiment 05 Water Hardness October 8th‚ 2013 The hardness of water was determined using the methods of titration‚ conductivity‚ and pH analysis. The mean and uncertainty of CaCO3 is 134±36.0 ppm. An error that could have potentially happened could be that the equivalence point was not correctly established causing inaccurate data. BACKGROUND: 1In hard water there is a high amount of mineral content present in the water. Most of the mineral content that is present

    Complexometric Determination of Water Hardness by EDTA Titration Bonnie Abella Dr. Asmita Kane Budruk 2/09/2014 Abstract: the complexometric EDTA titration was used to determine the salt substance in the water. This technique for the unknown sample 154 produced a water hardness of 8.43 x105=mg/L CaCO3 from the collected data which corresponds to the typical value from the city of Tempe. Introduction When the water from the rain collects impurities by dissolving the

    Complexometric Determination Of Water Hardness By Angelica Aquino CHM 152 LL January 5‚ 2013 METHODS: 1. Prepare an approximate 0.004 M disodium EDTA solution. To prepare this solution‚ weigh about 0.7-0.8 g of Na2EDTA and dissolve in 500 mL deionized water in your plastic bottle. Make to to shake the bottle to dissolve the salt. 2. Obtain a 250-mL Erlenmeyer flask and transfer a 10 mL of CaCO3 using a buret into the flask. 3. Measure 30 mL of deionized water and add it into the titration

    Hardness of Water by EDTA Titration Introduction Water hardness is caused by natural minerals that are dissolved into the water‚ predominantly calcium and magnesium‚ and is measured as the equivalent concentration of calcium carbonate (in milligrams per litre). Water hardness is usually noticed because of difficulty in lathering soap and the formation of a scum in the bathtub. Ca2+ and Mg2+ form insoluble salts with soaps causing precipitation of the soap scum. Another effect of hard water

    Practical 7: Determination of Hardness in Water | | | | | 10/3/2012 | | Aim: To determine the different types of hardness and alkalinity found in the water by titration methods. This is used to calculate the concentrations of calcium and magnesium found in the water. Principles: The hardness of water is determined to provide a measure of the quality of water for household and industrial use. Hard water is not a health hazard. Drinking hard water contributes a small amount of

    Complexometric Determination of Water Hardness Lab Report Introduction: In this lab the use of disodium salt of EDTA is used to determine the concentration of M^2+ metal ion impurities in hard water by chelometric titration. The indicator Eriochrome Black T will help detect when you EDTA has completely chelated the metal impurities. Chemical Principle: A complex ion consists of a metal ion with Lewis bases attached to it. These Bases form strong covalent bonds with the central complex
