7. Calculate the amount of lime (84%) and soda (92%) required for treatment of 20,000 litres of water, whose analysis is as follows: Ca(HCO3)2 = 40.5 ppm; Mg(HCO3)2 = 36.5 ppm; CaSO4 = 34 ppm; CaCl2 = 27.75 ppm; MgSO4 = 30.0 ppm; SiO2 = 3.5 ppm; NaCl = 10 ppm. Also calculate the temporary & permanent hardness of water sample
