4 litres of water obtained from a borewell in Vellore contains FeSO4 = 30.4 mg; CaSO4 = 13.6 mg; MgCl2 = 38 mg; Ca(HCO3)2 = 32.4 mg; Mg(HCO3)2 = 14.6 mg and NaCl = 11.7 mg. Calculate temporary, permanent and total hardness of the water sample in ppm. (Atomic masses of Fe = 56; Ca = 40; Mg = 24 and Na = 23)
Calculate the hardness of water in ppm CaCO3 if 25.00mL of the sample required 15.00mL of a 0.1000M EDTA to reach the endpoint. (MM CaCO3= 100.09g/mol). ** Need asap pls. Thanks.
Concentration EDTA (M): 1.94e-3 Trial #1 Trial #2 Trial #3 Volume of Water Sample titrated (mL): 25.00 25.00 25.00 Volume EDTA used (mL): 36.23 39.00 37.77 Calculate the average of the volume of EDTA used. Calculate the number of moles of EDTA solution required to titrate the water sample. The total hardness is due to one or a combination of Ca2+, Mg2+, and Fe2+ in your sample. It is convenient to express this hardness as though it was entirely due to Ca2+. Making this assumption, determine the number of moles of Ca2+ present in the bottled water sample. The total hardness and the information on Table 1 is always listed in parts-per-million (ppm) of CaCO3 (or mg CaCO3/KgH2O). Since the density of water is 1.0 g/mL, one ppm would be the same as the number of mg of CaCO3 per liter of water. Determine the number of moles of CaCO3 present in the bottled water, assuming all the Ca2+ combine with CO32−. Calculate the number of grams of CaCO3 present and convert to mg.…
