A student adds 0.15 mol of oxalic acid and 0.15 mol of sodium dihydrogen phospha

Question

A student adds 0.15 mol of oxalic acid and 0.15 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?

a. Oxalic acid is a weaker acid than phosphoric acid.

b. The hydrogen oxalate anion, HC2O4

a. Oxalic acid is a weaker acid than phosphoric acid.

b. The hydrogen oxalate anion, HC2O4

Explanation / Answer

c is the correct option

c ) Phosphoric acid is a weaker acid than oxalic acid.

reactions tend to form materials which are more stable, If H3PO4 is stable then It will not donate H+ that easily than oxalic acid.weak acids are more stable than strong acids because they don't donate H+ that easily or they don't dissolve in water that easily than strong acid.
