Sodium oxalate (Na₂C₂O₄), also known as disodium oxalate, is a white, crystalline solid with a variety of applications, including some specific uses in laboratories. Here’s a breakdown of its key properties, applications, and safety considerations:
Properties:
- Appearance: White crystalline solid
- Odor: Odorless
- Solubility: Low solubility in water, but increases with temperature
- Melting point: Decomposes above 290 °C (554 °F)
Description
Uses of Sodium Oxalate
- Standardizing Potassium Permanganate Solutions (Titration):
- In titrimetric analysis, a technique to determine the concentration of an unknown solution, sodium oxalate acts as a primary standard. This means it has a precisely known and highly reliable purity.
- Researchers use sodium oxalate solutions with a known concentration to standardize (determine the exact concentration) of potassium permanganate (KMnO₄) solutions. Potassium permanganate is a strong oxidizing agent used in many titrations.
- By accurately knowing the concentration of the sodium oxalate solution, researchers can then calculate the concentration of the potassium permanganate solution they are using for titrations. This ensures accurate measurements in subsequent experiments.
- Precipitation Reactions for Metal Ion Separation and Identification:
- Sodium oxalate can be a valuable tool in qualitative analysis experiments, which aim to identify the components present in an unknown solution.
- When sodium oxalate solution is added to a solution containing specific metal ions, it can trigger the formation of insoluble oxalate salts as precipitates (solid particles formed from a solution).
- Since different metal ions form oxalate salts with varying colors and solubilities, this precipitation reaction helps researchers separate and identify the specific metal ions present in the unknown solution based on the observed precipitate characteristics.

Agar Agar Powder
Agar agar powder refers to the dehydrated and powdered form of agar agar, a natural gelling agent derived from seaweed. It is made by drying and grinding the agar agar gel, resulting in a fine powder with excellent gelling properties. Agar agar powder is commonly used in cooking, baking, and food preparation as a vegetarian and vegan substitute for gelatin. It is prized for its ability to create firm and stable gels at relatively low concentrations and temperatures. Agar agar powder is versatile and can be used in a variety of recipes, including desserts, confectioneries, jams, jellies, and savory dishes.
