The Uses of Sodium ferrocyanide

Sodium Ferrocyanide is an anticaking agent and crystallizing agent. It is sometimes added as a crystallizing agent to salt when it crystallizes to generate lagged and bulky crystals which resist caking. It also functions as a water-soluble anticaking agent.

The Uses of Sodium ferrocyanide

Manufacture of sodium ferricyanide, blue pig- ments, blueprint paper, anticaking agent for salt, ore flotation, pickling metals, polymerization catalyst, photographic fixing agent.

Definition

ChEBI: Sodium hexacyanoferrate(4-) is a hexacyanoferrate(4-) salt.

General Description

Odorless yellow solid. Sinks and mixes with water.

Air & Water Reactions

Water soluble.

Reactivity Profile

Sodium ferrocyanide has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.

Health Hazard

None recorded.

Flammability and Explosibility

Non flammable

Safety Profile

When heated to decomposition emits toxic fumes of CN-.

Purification Methods

Crystallise it from hot water (0.7mL/g), until free of ferricyanide as shown by the absence of formation of Prussian Blue colour with ferrous sulfate solution.
