Water has total hardness of 155 mg/L as CaCO₃ and contains 0.004 M HCO₃^- at pH 7. What is the carbonate hardness and non-carbonate hardness in mg/L as CaCO₃? Would you use lime softening or lime-soda softening for this water and why?

Expert Solution

If alkalinity is less than total hardness then non carbonate harness will present.

A solution has a pH of 7.30 and an alkalinity of 25 mg/L as CaCO3. Essentially all of the alkalinity is contributed by the carbonate system. The water also contains 10–4.00 M Fe2+ (5.5 mg Fe2+/L). To remove the iron, oxygen is injected into the solution, converting the Fe2+ to Fe3+; the Fe3+ then precipitates as ferric hydroxide (Fe(OH)3(s)) according to the following reaction: Fe2+ + 0.25 O2(aq) + 2.5 H2O ⇌ Fe(OH)3(s) + 2 H+ What is the pH...
