Astudent adds 0.1 mol of oxalic acid and 0.1 mol of sodium dihydrogen phosphate to enough water to make 1.0 l of solution. 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.
