A water sample is found to contain 96 p p m of SO_(4)^(2-) and 122 p p m of HCO_(3)^(ɵ) with Ca^(2+) ion as the only cation. a. Calculate the p p m of Ca^(2+) in water. b. Calculate the mol of CaO required to remove HCO_(3)^(ɵ) ion form 1000 kg of the water c. Calculate the concetrated of Ca^(2+) in p p m remaining in water after adding CaO .

A sample of hard water contains 122 p p m of HCO_(3)^(ɵ) ions,. What is the minimum weight of CaO required to remove ions completely from 1 kg of such water sample?

A water sample is found to contain 96 ppm of SO_4^(2-) and 122 ppm of HCO+3^(ɵ) with Ca^(2_) ion as the only cation. (a). Calculate the ppm of Ca^(2+) in water. (b). Calculate the " mol of "CaO required to remove HCO_3^(ɵ) ion from 1000 kg of the water. (c). Calculate the concentration of Ca^(2+) in ppm remaining in water after adding CaO . (d). If the Ca^(2+) ion in 1 L of The treated water are completely exhange with H^(o+) ions, what will be its pH.
