The mineral analysis below was reported for a water sample. Calcium 40 Chloride 11 Magnesium 10 Sulfate 67.2 Potassium 7.0 Bicarbonate 109.6 Strontium 22.3 Note: All reported as mg/L as the ion unless stated otherwise. a. Draw a bar chart that includes all the ions listed above. (Remember to convert to appropriate units) b. What is the total hardness of the water using ALL multivalent cations in mg/L as CaCO3? c. What is the total hardness of the water using the predominant polyvalent cations in mg/L as CaCO3? d. What is the percent error in using only the predominant polyvalent cations? e. What is the carbonate hardness of the water in mg/L as CaCO3? f. What is the non-carbonate hardness of the water in mg/L as CaCO3? g. Would you characterize this water as hard or soft? Explain your answer. h. Do you think this water is more likely a surface water or a ground water? Explain your answer.
