Question 4: The wastewater from a restaurant contains organic matter with a theoretical oxygen demand of 2500 mg/L. If the average composition of the organic constituents in the water is C15H32O12, estimate the concentration of dissolved organic carbon (DOC) in the water.
Question 5: Neutral ammonia (NH3) is far more toxic to fish than ammonium ion (NH4 +) is. If a solution contains 10-4 M NH4 +, what is the acceptable pH range for keeping the NH3 concentration less than 10-6 M?
Question 6: A solution contains 3 x 10-4 M H2CO3 and 1.5 x 10-3 M HCO3 -. How much CO3 2- is in the solution?
