#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
#1 [5 pts) 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.
#12 ofwQ The "hardness" of a water sample is a measure of Select one O a. the total concentration of cations present in the sample O b. the sum of concentrations of calcium and magnesium ions in the sample O c. the sum of concentrations of all ions, cations and anions, in the water sample O d. the concentration of calcium ions in the water sample O e. the concentration of sulfate and carbonate ions in the water sample
