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. Organic material within the bauxite, conventionally considered to be composed of a broad variety of compounds including humates, fulvates and lower molecular weight material, is extracted from the bauxite through digestion. your answer is : pH = 8.98. the pH comes from the hydrolysis with C2O4-2, though some HC2O4- is made its further hydrolysis is very insignificant Sodium oxalate is stronger as an oxidizing agent, not as a reducing agent. Sodium Oxalate, ACS Safety Data Sheet according to Federal Register / Vol. v3.espacenet.com. 7 matches found for na2c2o4. Oxalic acid has pKa values of 1.250 (pKa1) and 4.266 (pKa2). So if you really mean "reducing agent" for these two, it would have to be H2O2, although that is a fairly strong oxidizing agent, too.
