Question

7)Calculate the temporary, permanent and total hardness of the water sample containing following salts-
Ca(HCO3)2 = 8.1ppm, CaCl2 = 11.1 ppm. MgCl2 =19.0 ppm. MgSO4 = 12.0 ppm
8) A sample of hard water gave on analysis the following result, calculate total Ppm Hardness in ppm.
Mg(HCO3)2 = 7.3 mg/lit, Ca(HCO3)2 = 81 mg lit, CaSO=27.2 mg/lit, CaCl. = 11.1 mg/lit
9) A sample of hard water give on analysis the following result Calculate the total hardness of Water,
Ca(HCO3)= 81 mg 1. Mg(HCO3)2 =14.6 mgl. Caso. = 6.8 mgl MgSO, = 27.2 mg 1. CaCl. = 19 mg 1.
10) Following salts were found in a water sample Find out temporary hardness, permanent hardness and total hardness of wat
sample.
CaCl. = 11.1 ppm MgCl = 4.75 ppm. Ca(HCO3)2 = 8.1 ppm. Mg(HCO3)2 = 75 ppm
11) A sample of water contains following percentage of salts. Calculate the temporary hardness. pennanent hardness andtotal
hardness of sample water
CaSO. - Ó S mg 1. CaCl. = 11.1 mg l MgSO. = 6.0 mg l. Moch
