Question

A wastewater is simulated as an ideal solution containing 10-2.5 M NaHCO3 and 10-3 M NH4Cl. The utility hopes to remove nitrogen from the solution by volatilizing NH3 gas. To prepare for that step, 148 mg/L Ca(OH)2 (lime) will be added to raise the pH and convert to the NH3(aq) form. The pH before and after lime addition. (Assume that no CaCO3 precipitation or ammonia loss takes place during lime addition; i.e., all species remain in solution.) would be
