Ph 8~9 High purity Sodium Acetate C2H3NaO2 58%~60% for Buffer Agent

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)

Application of sodium acetate in electroplating industry

1. Improve the uniformity of coating
Principle of action:

Sodium acetate can improve the dispersion ability of the plating solution,

so that metal ions are more uniformly deposited on the surface of the workpiece.

By improving the dispersion ability of the plating solution, the thickness difference of the coating is reduced

and the uniformity of the coating is improved.

Application scenario:

Complex shape workpiece: Used for plating complex shape workpiece to ensure uniform coating coverage.

2. Improve coating adhesion
Principle of action:

Sodium acetate can enhance the adhesion between the coating and the substrate and prevent the coating from peeling.

By improving the wettability of electroplating solution, the binding force between coating and substrate is increased.

Application scenario:

High-strength coating: Used for coatings requiring high adhesion, such as wear-resistant coatings and anti-corrosion coatings.

3. Improve the gloss of the coating
Principle of action:

Sodium acetate can improve the gloss and brightness of the coating and make the coating more beautiful.

The surface finish of the coating is improved by adjusting the chemical properties of the plating solution.

Application scenario:

Decorative coating: Used to electroplate decorative workpieces, such as jewelry, tableware and auto parts.

4. Prevent coating defects
Principle of action:

Sodium acetate reduces defects in the plating, such as pinholes, pitting and cracks.

By stabilizing the chemical properties of the plating solution, the occurrence of coating defects is reduced.

Application scenario:

High quality coating: For workpieces requiring high quality coating, such as electronic components and precision parts.
