1.74
form 
Powder
color 
white to yellow
Water Solubility 
very soluble H2O, alcohol, glycerol; insoluble ether [MER06]

Diamond Hazard Value Description
1
3 0
Health   3 Short exposure could cause serious temporary or moderate residual injury (e.g. liquid hydrogen, sulfuric acid, calcium hypochlorite, hexafluorosilicic acid)
Flammability   1 Materials that require considerable preheating, under all ambient temperature conditions, before ignition and combustion can occur. Includes some finely divided suspended solids that do not require heating before ignition can occur. Flash point at or above 93.3 °C (200 °F). (e.g. mineral oil, ammonia)
Instability   0 Normally stable, even under fire exposure conditions, and is not reactive with water (e.g. helium,N2)

POTASSIUM SULFIDE Chemical Properties,Uses,Production

Chemical Properties

colourless solid; turns brownish-red on

Chemical Properties

Potassium sulfide is a brownish-red crystalline solid.

Uses

Reagent in analytical chemistry, depilatory, medicine.

General Description

A red crystalline solid. Denser than water. Contact may severely irritate skin, eyes and mucous membranes. May be toxic by ingestion.

Air & Water Reactions

May spontaneously ignite with exposure to air. Deliquescent. Water soluble

Reactivity Profile

A reducing agent. So readily oxidized as to be pyrophoric in air [Bretherick 1979 p. 120]. POTASSIUM SULFIDE is incompatible with chloroform and nitrogen oxide.

Hazard

Flammable, dangerous fire risk, may ignite spontaneously, explosive in the form of dust or pow- der.

Health Hazard

TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may 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

Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.

Safety Profile

Poison by ingestion and inhalation. Emits H2S in contact with acids; steam. A flammable solid. Unstable; may explode on percussion or rapid heating. Ignites on contact with nitrogen oxide. Reacts with H2O to form KOH and KSH. When heated to decomposition it emits very toxic fumes of K2O and SOx. See also SULFIDES.

Potential Exposure

Potassium sulfide is used as a reagent in analytical chemistry; and in pharmaceutical preparations.

Shipping

UN1382 Potassium sulfide, anhydrous or Potassium sulfide with <30% water of crystallization, Hazard Class: 4.2; Labels: 4.2-Spontaneously combustible material.

Incompatibilities

May explosively decompose from shock, friction, or concussion. Dust or granules may spontaneously ignite on contact with air. The aqueous solution is a strong base; reacts violently with strong acids and acid fumes. The solid material decomposes on contact with acids producing hydrogen sulfide, and oxidizers producing sulfur dioxide.
