0.00012% MgSO_(4) and 0.000111% CaCl_(2) is present in water. What is the measured hardness of water and millimoles of washing soda required to purigy water 1000 L water ?

A 50 mL sample of hard water containing Ca^(2+) and Mg^(2+) ions is titrated with 50 mL. 0.005 M EDTA solution at pH=10 , using eriochrome balck -T indicator to reach equivalence point. In a equal amount of hard water sample, Mg^(2+) ions are precipitated as Mg(OH)_(2) by adding suitable amount of NaOH . the solution, after precipitation of Mg(OH)_(2) , is stirred and then titrated with EDTA solution using calcon as indicator, and it requires 10 mL of above EDTA solution to reach equivalence point. a. Calculate the strength of Ca^(2+) and Mg^(2+) ions present in hard water. b. Calculate the hardness due to Ca^(2+) ions in p p m of CaCO_(3) . c. Calculate the hardness due to Mg^(2+) ions in p p m of CaCO_(3) . d. Calculate the total hardness of water in p p m of CaCO_(3) .
