While visiting Zagreb, Croatia, Mr. Arthur Van de Lay visits the Mimara Art Museum and then takes in the great architecture of the city. He stops at a café in the old town and orders a bottle of mineral water. The reported chemical concentration of this water is: [Na+] = 0.65 mg/L, [K+] = 0.4 mg/L, [Mg2+] = 19 mg/L, [Ca2+] = 35 mg/L, [CI-] = 0.8 mg/L, [SO42-] = 14.3 mg/L, [HCO3-] = 189 mg/L. (a) Which of these chemicals would you use to calculate hardness? (b) All aqueous solutions must maintain charge neutrality. Another way to state this is that the sum of all cations on an equivalent basis must equal the sum of all anions on an equivalent basis (within 5%). Thus, water samples can be checked to determine whether something is incorrect in the analyses or a constituent is missing. Verify that the reported chemical concentrations listed above make sense based on the above information.
