1. The results of a water analysis are as follows: Ca2+ = 70 mg/L Mg2+ = 9.7 mg/L Na+ = 6.9 mg/L K + = 0.1 mg/L Cl- = 10.6 mg/L SO4 2- = 96.0 mg/L HCO3 - = 140.3 mg/L 1) Is this an acceptable analysis? Why or why not? 2) Draw a millequivalent bar graph showing meq/L for a cation and anion balance. 3) What dose of lime and soda ash would be required to treat this water to an acceptable hardness levels?

Expert Solution

Lime added at ratio of 1:1 or each CH and 2:1 for Mg(HCO3)2(2lime and 1 Mg(HCO3)2)

Lime added at ratio 1:1 for Magnesium NCH and NCH

Soda ash added at 1:1 for Magnesium or calcium NCH

Hard water often contains dissolved Ca2+ and Mg2+ ions. One way to soften water is to add phosphates. The phosphate ion forms insoluble precipitates with calcium and magnesium ions, removing them from solution. Suppose that a solution is 0.049 M in calcium chloride and 0.094 M in magnesium nitrate. What mass of sodium phosphate would have to be added to 1.4 L of this solution to completely eliminate the hard water ions? Assume complete reaction. Enter a numerical answer in...
