A student 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.
can someone give me explanations why EACH one isn't or is the right answer. I'm studying for a test but want to understand the concept. the answer is C

The lattice enthalpy (formation of ionic solid from ions in the gas phase) for agcl(s) is -916 kj/mol and the hydration enthalpy (dissolution of gaseous ions into water) is -850 kj/mol. how much heat (in joules) is involved in forming 1l of saturated agcl solution (1.8 × 10-4 g / 100 ml water) by dissolving agcl(s)? assume solution volume does not change much upon dissolution. the equations are given below. ag+(g) + cl−(g) æ agcl(s)
