The following equilibrium is established with the concentrations of the products greater than the concentrations of the reactants. Which of the statements about the equilibrium system is correct?
H2C2O4(aq) + H2PO4–(aq) HC2O4–(aq) + H3PO4(aq)
A) Oxalic acid is a weaker acid than phosphoric acid. B) The hydrogen oxalate anion, HC2O4-, is a stronger base than the dihydrogen phosphate anion, H2PO4- .C) Phosphoric acid is a weaker acid than oxalic acid. D) The dihydrogen phosphate anion, H2PO4-, is a stronger acid than oxalic acid. E) Water is a stronger acid than either oxalic or phosphoric acids.
