Trihydrate White Crystal Sodium Acetate 58%~60% for Electroplating Industry

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. Plating solution additive
Principle of action:

Sodium acetate can be used as an additive in the plating solution to improve the quality

and properties of the coating.

By adjusting the chemical properties of the plating solution, the uniformity,

gloss and adhesion of the coating are improved.

Application scenario:

Nickel plating: Adding sodium acetate to nickel plating solution can

improve the brightness and corrosion resistance of the coating.

Galvanizing: Adding sodium acetate to the galvanizing solution can

improve the uniformity and adhesion of the coating.

2. Buffer
Principle of action:

Sodium acetate aqueous solution is weakly alkaline

and can be used as a buffer to stabilize the pH value of the electroplating solution.

The stability of the plating process is ensured by preventing the acid-base fluctuation of the plating solution.

Application scenario:

Acidic electroplating solution: Adding sodium acetate to

the acidic electroplating solution can neutralize excess acid and stabilize pH.

Alkaline electroplating solution: Adding sodium acetate to alkaline electroplating solution can

prevent the pH value from being too high.

3. Complexing agent
Principle of action:

Sodium acetate can form complexes with certain metal ions and change its chemical properties.

The solubility and stability of metal ions in electroplating solution were improved by complexation.

Application scenario:

Copper plating: Adding sodium acetate to the copper plating solution can

improve the solubility of copper ions and the uniformity of the coating.

Silver plating: Adding sodium acetate to the silver plating solution can improve the

stability of silver ions and the gloss of the coating.

4. Conductive salt
Principle of action:

Sodium acetate can be used as a conductive salt to improve the conductivity of electroplating solution.

The electroplating efficiency and coating quality can be improved by increasing the conductivity of electroplating solution.

Application scenario:

Chromium plating: Adding sodium acetate to the chromium plating solution can

improve the conductivity of the electroplating solution and the uniformity of the coating.

Gold plating: Adding sodium acetate to the gold plating solution can improve the plating efficiency and gloss of the coating.
