A sample of tap water contains 366 ppm of `HCO_(3)^(-)`ions with `Ca^(2+)` ion. Now `Ca^(2+)` removed by Clark's method by addition of `Ca(OH)_2`. Then what minimum mass of `Ca(OH)_2` will be required to remove `HCO_(3)^(-)`ions completely from 500 g of same tap water

A sample of hard water contains 96 pp m."of" SO_(4)^(2-) and 183 pp m "of" HCO_(3)^(-) , with Ca^(2+) as the only cation. How many moles of CaO will be required to remove HCO_(3)^(-) from 1000 kg of this water? If 1000 kg of this water is treated with the amount of CaO calculated above, what will be the concentration (in ppm)of residual Ca^(2+) ions (Assume CaCO_(3) to be completely insoluble in water)? If the Ca^(2+) ions in one litre of the treated water are completely exchange with hydrogen ions, what will be its pH (One ppm means one part of the substance in one million part of water, weight // weight)?

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 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?

10^(5)g of a sample of water contained 16.2 8 of Ca(HCO_(3))_(2) Its hardness is

10^5 g of a sample of water contained 16.2 g of Ca(HCO_3)_2 its hardness is

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 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.
