How much oxygen will be required and how much hydrogen will be produced if wastewater containing $240 \mathrm{mg} / \mathrm{L}$ acetate is treated using the following designs: (a) microbial fuel cell and (b) microbial electrolysis cell.

Question

Accepted Answer

∻Answer∻ ⚹ The amount of oxygen required and hydrogen produced in the treatment of wastewater containing 240 mg/L acetate cannot be determined without additional information such as the stoichiometry of the reactions involved in the microbial fuel cell and microbial electrolysis cell processes. ⚹ ∻Solution∻ ‖ a ⋮ To calculate the amount of oxygen required and hydrogen produced, the chemical reactions for the microbial fuel cell and microbial electrolysis cell must be known. ‖ ‖ b ⋮ The stoichiometric coefficients from the balanced chemical equations would then be used to calculate the moles of oxygen consumed and hydrogen produced per mole of acetate. ‖ ‖ c ⋮ The molar mass of acetate (C2H3O2-) is needed to convert the given concentration from mg/L to moles/L. ‖ ‖ d ⋮ Finally, using the stoichiometry and the concentration of acetate, the amounts of oxygen and hydrogen can be calculated. ‖ ∻Key Concept∻ ⚹ Stoichiometry of chemical reactions ⚹ ∻Explanation∻ ⚹ Stoichiometry is essential to determine the amounts of reactants consumed and products formed in a chemical reaction. Without the specific reactions and their stoichiometry, it is not possible to calculate the required oxygen and produced hydrogen. ⚹◊What metabolic processes occur in a microbial fuel cell and a microbial electrolysis cell during wastewater treatment? ⍭ Generate me a similar question◊
