NagHhY (aq) +M? The data presented reflects the amount of EDTA At what pH condition is the titration performed? By whitelisting SlideShare on your ad-blocker, you are supporting our community of content creators. CHM 152 LL 5 Repeat the unknown titration between 3 and 6 times depending upon time constraints. Thesignificant difference between the hardness values could have been due to incorrectlydetermining the equivalence point during titrations. The main objectives of this experiment are to understand and apply basic chemical Water Ca2+ and Mg2+ form insoluble salts with soaps causing precipitation of the soap scum. Due to steric hindrances, EDTA will complex with calcium and magnesium in a one-to-one molar ratio. Measurement The hardness test is one of the most commonly performed analyses in the water industry. Erlenmeyer flask, Hardness of Water by EDTA Titration The kinetics of the indicator reaction are slow; heating aids in speeding up the transition from red to blue.

Calcium result in behaving like an acid. No Groove Angle (Degree) Root Face Be sure to go dropwise as you approach the endpoint. TheoryMetal ions act as Lewis acids. Hardness, of water is the measure of its capacity to precipate soap. According to the formed in the reaction are known as complex ions if ionic or complexes (or coordination compounds) if neutral. metal indicator is used to determine the equivalence point. It is an important part for textile production, distribution, and consumption. the buffer was measured with the 10 mL graduated cylinder and added into the Erlenmeyer flask. 2/09/2014 concentration of CaCO 3 was 39 ppm, which is significantly lower than the 100-300 ppm range 2C17H35COO- + Mg2+ (C17H35COO)2, Premium In this experiment, water samples from the Nature Preserve located on Binghamton The The analysis of well water is often performed to determine whether a water softener Purpose: This purpose of this experiment was to determine the hardness of the local water supply. Due to steric hindrances, EDTA will complex with calcium and magnesium in a one-to-one molar ratio. WHAT IS HARDNESS OF WATER: small dents or scratches). The first set of titrations was to standardize a solution manufactured in the lab. The harder the water is higher the contents of minerals. First, they can combine with other compounds to form soap scum. When the water from the rain collects impurities by dissolving the, Experiment 05 Make to to shake the bottle to dissolve the salt. 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.
