#1 A water sample contains 60 mg/L of calcium, 60 mg/L of magnesium, and 25 mg/L of sodium. Assuming the alkalinity of the water is 394 mg/L CaCO3. Estimate Total Hardness, Carbonate Hardness, and Noncarbonate Hardness using all polyvalent cations. #2 What is the % error using only the predominant cations? #3 Construct a bar chart to determine the speciation of the hardness
A water sample has a total hardness of 275 mg/L as CaCO3 and a total alkalinity of 320 mg/L as CaCO3. What are the carbonate and non-carbonate hardness (in mg/L as CaCo2) of the water sample? Use the relationship when alkalinity < total hardness, carbonate hardness(mg/L) - alkalinity(mg/L) and when alkalinity >/= total hardness Carbonate hardness(mg/L) -totalk hardness(mg/L) if necessary
