Sodium oxalate is a white crystalline powder with the chemical formula Na2C2O4. It is commonly used in analytical chemistry as a reducing agent, a complexing agent, and a standard for measuring calcium ions.

If you have 500g of sodium oxalate, it is important to handle it with care as it can be harmful if ingested, inhaled or comes into contact with the skin or eyes. Always wear appropriate personal protective equipment (PPE), such as gloves, goggles, and a lab coat when handling this substance.

In terms of storage, sodium oxalate should be kept in a tightly closed container in a cool, dry, and well-ventilated area away from incompatible materials such as acids and oxidizers.

If you are planning to use sodium oxalate in an experiment, it is important to follow proper safety protocols and dispose of any unused material appropriately. Consult with your institution’s safety guidelines or a trained safety professional for guidance.
