Answer #1

Mn2+ binds with two nitrates to form Mn(NO3)2.

Whereas Fe2+ does also bind with two nitrates to form Fe(NO3)2.

Hence, the concentration of NO3- is twice the total concentration of Mn2+ and Fe2+.

i.e. If the total concentration of Mn2+ and Fe2+ is x M, then the concentration of NO3- is 2x M.

    2. (12 points). You need to soften a water that has high concentrations of dissolved calcium and magnesium. (a) You measure the Cat concentration as 55 mg/L and the Mg concentration as 10 mg/L. What are these concentrations in units of mM? (b) One possible treatment operation to soften the water is to precipitate the calcium and magnesium as solids. The total carbonate species here is 16 mm. In this case, you recommend raising the pH where both CaCO., and...
