Usage

Description

Sodium copper cyanide, also known as sodium cyanide copper, is a white, crystalline double salt of copper cyanide and sodium cyanide. It is a colorless to light yellow liquid that is denser than water. Sodium copper cyanide may cause irritation to the skin, eyes, and mucous membranes upon contact and is toxic if ingested, inhaled, or absorbed through the skin. It is soluble in water and is commonly used in the preparation and maintenance of cyanide copper plating baths.

Uses

Used in Electroplating Industry:
Sodium copper cyanide is used as a key component in the preparation and maintenance of cyanide copper plating baths. It provides a smooth and bright finish to the plated metal surfaces, enhancing their appearance and corrosion resistance. The cyanide ions in the compound help to dissolve the copper anodes, allowing for a uniform distribution of copper ions in the plating solution.
In addition to its primary use in electroplating, sodium copper cyanide may also find applications in other industries where copper plating is required, such as in the manufacturing of electronics, automotive components, and decorative items. Its ability to produce a high-quality finish makes it a valuable asset in these industries. However, due to its toxic nature, proper safety measures and handling procedures must be followed to minimize the risk of exposure and potential health hazards.

Air & Water Reactions

Soluble in water.

Reactivity Profile

SODIUM CUPROCYANIDE SOLUTION is an aqueous solution containing an inorganic cyanide. Sodium copper cyanide reacts with acids to evolve hydrogen cyanide, which is a highly toxic and flammable gas.

Hazard

Toxic material.

Health Hazard

TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

Fire Hazard

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Vapors may accumulate in confined areas (basement, tanks, hopper/tank cars etc.). Substance will react with water (some violently), releasing corrosive and/or toxic gases and runoff. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water.

Safety Profile

A poison. When heated to decomposition it emits toxic fumes of CN-
