CAS 6131-90-4 58%~60% Sodium Acetate White Particle for pH Regulator Origin WeiFang

Sodium acetate properties

1. Chemical properties
Chemical formula: CH₃COONa

Molecular weight: 82.03 g/mol (anhydrous matter); 136.08 g/mol (trihydrate)

Structure: Composed of the radical acetate ion (CH₃COO⁻) and sodium ion (Na +).

pH value: The aqueous solution is weakly alkaline, pH is about 8-9.

2. Physical properties
Appearance:

Anhydrous sodium acetate: white crystalline powder.

Sodium acetate trihydrate (CH₃COONa·3H₂O) : colorless transparent crystal.

Solubility:

Soluble in water, solubility increases significantly with temperature (at 20°C, about 46.5 g per 100 mL of water).

Slightly soluble in ethanol, insoluble.

Melting point:

Anhydrous sodium acetate: 324°C.

Sodium acetate trihydrate: 58°C (dehydration decomposition).

Density:

Anhydrous sodium acetate: 1.528 g/cm³.

Sodium acetate trihydrate: 1.45g /cm³.

Hygroscopic: Sodium acetate trihydrate is easy to hygroscopic, and anhydrous sodium acetate hygroscopic is low.

3. Thermal stability
Heated decomposition. When heated to high temperatures, sodium acetate decomposes to

form sodium carbonate (Na₂CO₃) and methane (CH₄)

How about sodium acetate PH regulator

1. Principle of sodium acetate as a pH regulator
Weakly basic:

Sodium acetate is a salt formed by the reaction of a weak acid (acetic acid, CH COOH)

and a strong base (sodium hydroxide, NaOH), and its aqueous solution is weakly alkaline,

usually with a pH between 8.0-9.0.

Buffer effect:

Sodium acetate can be combined with acetic acid (CH COOH) to

form an aceto-sodium acetate buffer system to effectively stabilize the pH of the solution.

The pH range of the buffer system is usually between 4.5 and 5.5, which is suitable for

scenarios requiring a weakly acidic environment.

2. Advantages of sodium acetate as a pH regulator
Strong stability:

Sodium acetate can effectively resist the interference of external acid and base,

and keep the pH value of the solution stable.

Wide range of application:

Suitable for pH regulation in weakly acidic to weakly alkaline environments.

High security:

Sodium acetate has low toxicity to human body and environment and is safe to use.

Low cost:

Sodium acetate is cheap and suitable for large-scale use.

3. Main application areas
(1) Water treatment
Adjust pH value:

It is used to adjust the pH value of industrial wastewater and drinking water to

ensure that the water quality meets the standard.

Buffer system:

In wastewater treatment, sodium acetate and acetic acid form a buffer system to

stabilize pH and promote microbial growth.

(2) Food industry
Acidity regulation:

Used in beverages, dairy products and baked goods to regulate acidity and improve taste and shelf life.

Buffer:

In food processing, sodium acetate acts as a buffer to prevent pH fluctuations.

(3) Medicine and laboratory
Buffer solution:

It is used to prepare buffer solutions, stabilize the pH of pharmaceutical preparations

and biological experiments.

Drug synthesis:

In the process of drug synthesis, sodium acetate is used as a pH regulator to improve the reaction efficiency.

(4) Chemical industry
Reaction condition control:

In chemical reactions, sodium acetate is used to adjust the pH value of the reaction system to

improve the selectivity and yield of the reaction.

Electroplating industry:

In the plating solution, sodium acetate is used as a buffer to stabilize pH value and improve the quality of the coating.

4. Use precautions
Dosage control:

According to the specific application requirements, the amount of sodium acetate should be

controlled reasonably to avoid excessive use.

Safety protection:

Sodium acetate is less toxic to humans, but it is still necessary to wear protective gear

and avoid direct contact with skin and eyes.

Environmental impact:

Sodium acetate is environmentally friendly, but it still needs to be used rationally to avoid excessive emissions.
