Problem 4 – A laboratory report for a sample of water collected from a natural reservoir showed the following results: Concentration (mg/L) Component CO2 12.0 Ca2+ Mg2+ 30.0 70.0 Na+ 12.0 SO42- 240.0 Alkalinity pH 180 as CaCO3 7.1 a) Calculate total hardness, carbonate hardness, and noncarbonate hardness. b) Draw a bar chart that clearly depicts the total hardness, carbonate hardness, and noncarbonate hardness. c) Calculate the calcium carbonate hardness, the calcium non-carbonate hardness, the magnesium carbonate hardness, and the magnesium non-carbonate hardness. d) Based only on that water sample, would you use the water directly from the reservoir for domestic use? Why? If not, would you make a recommendation for the water to be treated before consumption? Given: Equivalent Weight (mg/meg) Component Ca2+ 20.0 Mg2+ 12.2 Na+ 23.0 so,2- 48.0 Alkalinity 50.0
