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
