Overview
This material contains potassium hydrosulfide in solution. It will have a rotten egg like odor. It has a pH between 8.5-11.5. It is a transparent to dark green liquid. Contact with heat or acidic materials will evolve highly toxic hydrogen sulfide. The liquid is highly corrosive to the skin and eyes. Ingestion causes severe burning and corrosion in all portions of the gastrointestinal tract.

Hazard information
Hazards Summary
Usually found as the hemihydrate; Quickly turns yellow on exposure to air forming polysulfides and hydrogen sulfide; [Merck Index] In solution, reacts with water and may form hydrogen sulfide; Corrosive to skin and eyes; [CAMEO] May produce hydrogen sulfide gas on contact with air or stomach acids; Causes burns; Danger of irreversible effects; Inhalation may cause corrosive effects on the respiratory tract; [Strem MSDS] See Hydrogen sulfide.
Reactivity Profile
Inorganic sulfides are generally basic and therefore incompatible with acids. Many of these compounds are reducing agents and therefore react vigorously with oxidizing agents, including inorganic oxoacids, organic peroxides and epoxides. Simple salts of sulfides (such as sodium, potassium, and ammonium sulfide) react vigorously with acids to release hydrogen sulfide gas
