Usage

Chemical Properties

White, crystalline, double salt of cop- per cyanide and sodium cyanide. Soluble in water.

Uses

For preparing and maintaining cyanide copper plating baths based on sodium cyanide.

General Description

A colorless to light yellow liquid. Denser than water. Contact may irritate skin, eyes and mucous membranes. May be toxic by ingestion, inhalation and skin absorption.

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-
