Description
Sodium acetate anhydrous is a sodium salt of acetic acid, with the chemical formula C₂H₃NaO₂. It appears as a white, crystalline powder and is highly soluble in water. It is also a lab reagent available in Labtex Bangladesh at the reasonable price.
Chemical Properties
- Chemical Formula: C₂H₃NaO₂
- Molecular Weight: 82.03 g/mol
- Structure: Consists of an acetate ion (CH₃COO⁻) and a sodium ion (Na⁺).
- Appearance: White crystalline solid or powder.
- Density: Approximately 1.528 g/cm³.
- pH: Typically around 7 when dissolved in water.
Physical Properties
- Melting Point: 323 °C (613 °F), decomposes before boiling.
- Solubility: Soluble in water (1 g in about 1 mL at 20 °C), but insoluble in organic solvents like ethanol.
General Uses of Sodium Acetate Anhydrous
- Buffer Solutions:
- Sodium acetate is commonly used in buffer solutions in biochemical applications to maintain pH levels in biological experiments.
- Food Industry:
- Acts as a preservative and flavor enhancer, particularly in snacks and processed foods. It is often labeled as E262.
- Heating Pads:
- In reusable heat packs, sodium acetate can be supercooled in a liquid state and releases heat upon crystallization when a metal disc is flexed.
- Pharmaceuticals:
- Used in various medicinal formulations, including as a saline laxative.
- Chemical Synthesis:
- Serves as a reagent in organic synthesis and as a catalyst in certain reactions.
Synthesis
Sodium acetate can be synthesized through various methods, including:
- Neutralization Reaction:
- Mixing acetic acid with sodium hydroxide or sodium bicarbonate produces sodium acetate.
- Reaction: CH3COOH+NaOH→CH3COONa+H2O\text{CH}_3\text{COOH} + \text{NaOH} \rightarrow \text{CH}_3\text{COONa} + \text{H}_2\text{O}CH3COOH+NaOH→CH3COONa+H2O
Safety and Handling of Sodium Acetate
- Toxicity: Generally recognized as safe (GRAS) when used in food and pharmaceuticals. However, excessive consumption can lead to gastrointestinal disturbances.
- Handling: Should be handled with gloves and eye protection to avoid irritation, especially in powder form.
- Storage: Store in a cool, dry place in a tightly closed container to prevent moisture absorption.
Environmental Impact
C₂H₃NaO₂ is biodegradable and considered environmentally friendly lab reagent, but large quantities should be managed to avoid potential water contamination.
