3. Determine the lime and soda ash dose, in mg/L as Ca(OH)2 and Na2CO3, to soften the water of a village to a final hardness of 40.0 mg/L as CaCO3. Chemical analysis showed that the water contains Na+ (50 mg/L), Ca2+ (150 mg/L), Mg²+ (30 mg/L, HCO3 (100 mg/Las CaCO3), Cl (80 mg/L). and CO2 (5.0 mg/L).
