Disodium oxalate Chemical Properties,Uses,Production

Physical Properties

White crystalline powder; density 2.34 g/cm3; decomposes around 250° C; sparingly soluble in water, 3.7 g/100 mL at room temperature; moderately soluble in boiling water, about 6.25 g/100 mL; the aqueous solution is practically neutral; insoluble in alcohol

Uses

Sodium oxalate is used as an analytical standard for standardization of potassium permanganate and other strong oxidizing agents. It also is used in finishing textiles, tanning leather, and blue printing.

Preparation

Sodium oxalate can be made by heating sodium formate at about 250°C:
2HCOONa → Na2C2O4 + H2
It also can be prepared by reacting oxalic acid with a dilute aqueous solution of sodium hydroxide followed by evaporation and crystallization.

Definition

ChEBI: An organic sodium salt consisting of sodium and oxalate ions in a 2:1 ratio.

Uses

Finishing textiles, tanning and finishing leather; for standardizing potassium permanganate solution.

General Description

Odorless white solid. Sinks and mixes slowly with water.

Reactivity Profile

Disodium oxalate gives basic aqueous solutions. Neutralizes acids in exothermic reactions. Can serve as a reducing agent in reactions that generate carbon dioxide.

Health Hazard

Inhalation or ingestion causes pain in throat, esophagus, and stomach; mucous membranes turn white; other symptoms include vomiting, severe purging, weak pulse, cardiovascular collapse, neuromuscular symptoms, and kidney damage. Contact with eyes or skin causes irritation.

Purification Methods

It crystallises from hot water (16mL/g) by cooling to 0o. Before use as a volumetric standard, analytical grade quality sodium oxalate should be dried for 2hours at 120o and allowed to cool in a desiccator. [Beilstein 2 IV 1819.]
