Hardness of water is 200 ppm. Calculate the molarity and normality of `CaCO_(3)` of the water

Hardness of water id 200 p p m . The normality and molarity of CaCO_(3) in the water is

Hardness of water is 200 ppm. The normality and molarity of CaCO_3 in the water is (a). 2xx10^(-6)(N,2xx10^(-6)M (b). 4xx10^(-2)N,2xx10^(-2)M (c). 4xx10^(-3)N,2xx10^(-3)M (d). 4xx10^(-1)N,2xx10^(-1)M

If hardness of water sample is 200 parts per million , Calculate the mass ratio of CaCO3 to water is:

Hardness of water sample is 300 ppm CaCO_3 Hence its molarity is:

Hardness of water sample is 300 ppm CaCO_3 Hence its molarity is:

Hardness of a water sample is 100 "ppm" CaCo_(3) . Thus molarity of CaCO_(3) is

100 mL sample of hard water is titrated with 500 " mL of " 0.001 M EDTA solution at pH=10 , using eriochrome black-T indicator to reach equivalence point. An equal another amount of hard water sample is boiled for 30 min. After filtration and cooling, the same sample is titrated with 200 " mL of " 0.011 M EDTA solution at pH=10 using Mg-EDTA complex solution and erichrome black-T indicator to reach equivalence point. (i). Calculate the total hardness of water sample (temporary + permanent) in ppm of CaCO_3 . (ii). Calculate the permanent hardness of water sample in ppm of CaCO_3 . (iii). Calculate the temporary hardness of water sample in ppm of CaCO_3

100 mL sample of hard water is titrated with 500 mL of 0.001 MEDTA solution at pH=10 , using eriochrome black -T indicator to reach equivalence point. An equal another amount of hard water sample is boiles for 30 mi n . After filtration and cooling, the same sample is titrated with 200 mL of 0.001 M EDTA solution at pH=10 using Mg-EDTA complex solution and erichrome black -T indicator to reach equivalence point. a. Calculate the total hardness of water sample (temprary +permanent) in p p m of CaCO_(3) . b. Calculate the permanent hardness of water sample is p p m of CaCO_(3) . c. Calculate the temporary hardness of water sample is p p m of CaCO_(3) .

A hard water sample contains dissolved Mg(HCO_3)_2 only. If degree of hardness of that sample is 150ppm, calculate the weight of Mg(HCO_3)_2 present in 1kg of water sample.

A hard water sample contains calcium chloride only degree of hardness with 200 ppm. Calculate the weight of calcium chloride present in 10 kg of water sample.
