1) The reaction for the coagulation of water with alum is shown below. a. Balance the equation. Al2(SO4)3.18H2O + Aluminum sulfate (alum) HCO3- ←→ __AI(OH)3 + CO₂+ _H2O+ SO2- Bicarbonate precipitate ion b. If 125 mg/L of bicarbonate is in the water and the plant treats 432,000 L/d, how much aluminum hydroxide precipitate will the treatment plant operator need, to dispose of daily (in kg/d)?
