The analysis of water quality from an artesian well presented the result Alkalinity at bicarbonates equal to 24 (mg/L CaCO3), the pH of 7.0, the concentration of Ca+2 equal to 14 mg/L and the Mg+2 concentration equal to 20 mg/L. Knowing that the equivalent weight of CaCO3 is equal to 50, of Ca+2 equal to 20 and of Mg+2 equal to 12. It is concluded that the permanent and temporary hardness, respectively, are: (A) 24mg/L (CaCO3) e 118 mg/L (CaCO3). (B) 94 mg/L (CaCO3) e 24 mg/L (CaCO3). (C) 24 mg/L (CaCO3) e 94 mg/L (CaCO3). (D) 94 mg/L (CaCO3) e 118 mg/L (CaCO3

The analysis of water quality from an artesian well presented the result Alkalinity at
bicarbonates equal to 24 (mg/L CaCO3), the pH of 7.0, the concentration of Ca+2 equal to 14 mg/L and the
Mg+2 concentration equal to 20 mg/L.
Knowing that the equivalent weight of CaCO3 is equal to 50, of Ca+2 equal to 20 and of Mg+2 equal to 12.
It is concluded that the permanent and temporary hardness, respectively, are:

(A) 24mg/L (CaCO3) e 118 mg/L (CaCO3).
(B) 94 mg/L (CaCO3) e 24 mg/L (CaCO3).
(C) 24 mg/L (CaCO3) e 94 mg/L (CaCO3).
(D) 94 mg/L (CaCO3) e 118 mg/L (CaCO3).
