What Is Sodium Acetate Structure? A Clear Guide

Sodium acetate, also known as sodium ethanoate, is a sodium salt of acetic acid and has the chemical formula CH3COONa. It is a white, crystalline powder that is highly soluble in water and has a wide range of applications in various industries, including food, pharmaceuticals, and textiles.

Chemical Structure

The chemical structure of sodium acetate consists of a sodium ion (Na+) and an acetate ion (CH3COO-). The acetate ion is derived from acetic acid (CH3COOH), where the hydrogen atom is replaced by a sodium ion. The resulting structure is a sodium cation and an acetate anion, which are held together by electrostatic forces.

The molecular structure of sodium acetate can be represented as:

CH3COONa

Where:

• CH3- is the methyl group
• COO- is the carboxylate group
• Na+ is the sodium ion

Physical Properties

Sodium acetate is a highly soluble compound in water, with a solubility of approximately 250 g/100 mL at 20°C. It is also soluble in ethanol and slightly soluble in ether. The compound has a melting point of approximately 324°C and a boiling point of 881°C.

Applications

Sodium acetate has a wide range of applications in various industries, including:

• Food industry: Sodium acetate is used as a food additive, where it serves as a preservative, flavor enhancer, and texture modifier.
