According to the Bronsted/Lowry theory of acids and bases, the oxalate ion a conjugate base derived from oxalic acid (it is the conjugate base of hydrogen oxalate [HC2O4]1- as oxalic acid is diprotic) . Oxalic acid is a weak acid, meaning that it establishes an equilibrium in water rather than dissociate 100% (as a strong acid would). This equilibrium is established when the conjugate base is strong enough to mount an effective reverse reaction and pull the proton back. The general rule is that the weaker the acid, the stronger the conjugate base.
So, sodium oxalate is a salt of oxalic acid and it contains a conjugate base from the oxalic acid equilibrium system.
When sodium oxalate is dissolved in water, it dissociates completely into aqueous sodium ions and aqueous oxalate ions.
The oxalate ions will behave like a base with water in the following reaction: [C2O4]2-(aq) + H2O (l) = [HC2O4]1-(aq) + [OH]1-(aq)
The presence of the hydroxide ions in the solution will result in the solution having a slightly basic pH.

Sodium oxalate could be considered an acid if it is mono-basic. If it is dibasic it is a salt of an acid and is still not considered a base, since it does not generate hydroxide ion when dissolved in water.

Any acid that is dibasic is able to disassociate two protons or Hydrogen cations when dissolved in water and that's what oxalic acid also does so it's a dibasic acid.

Sodium oxalate dissolve in water to make a basic solution.
We can predict that because sodium is found in a strong base, and oxalate is found in a weak acid. Sodium oxalate is the salt of the Arrhneius acid base reaction. H2C2O4(aq) + 2NaOH(aq) → Na2C2O4(aq) + 2HOH(l)
The oxalate ion will hydrolyze (react with water) to make HC2O4^- acid and OH- ions. The OH- ions make the solution basic. C2O4^2- + HOH(l) → HC2O4^- + OH-

If the answer is: sodium oxalate is a base, the answer is partially correct.
First of all, actually two sodium oxalate are possible: monobasic (NaOOC-COOH) and this product is an acid salt that in water shows a pH acid (in the range 4–5 depending on the concentration).
Usually, when you write “sodium oxalate” you mean the disodium oxalate (NaOOC-COONa), because the monosodium oxalate is not a common product . The disodium salt is formed by a strong base (NaOH) and a weak bicarboxylic acid. Therefore, when you dissolve it in water the salt dissociated in 2Na+ and –OOC–COO– . This last goes in equilibrium with water and you will obtain:
–OOC–COO– + H2O → HOOC–COO– + OH–
HOOC–COO– + H2O → HOOC–COO+ OH–
The presence of OH– give you a pH basic (in the range 9–10 depending on the concentration).
Just to conclude the correct answer is: “neutral sodium oxalate is a salt partially hydrolysed” therefore, in aqueous solution is basic and the final pH ranges between 9 and 10, depending on the concentration.

When we dissolve NaCl in water, we get sodium cations and chloride anions. These are, respectively, the conjugate acid of the strong base NaOH and the conjugate base of the strong acid HCl. That means sodium and chloride ions are very weak acids and bases by the Bronsted-Lowry definition and not even that by the Lewis definition (they're not capable of accepting or donating electron pairs). Of course, even if thou don't factor that in, the fact remains that their contributions to a solution's pH would balance each other out.
