Is potassium sulfide toxic?

* Potassium Sulfide is a HIGHLY CORROSIVE CHEMICAL and contact can severely irritate and burn the skin and eyes with possible eye damage. * Breathing Potassium Sulfide can irritate the nose and throat. * Breathing Potassium Sulfide can irritate the lungs causing coughing and/or shortness of breath.

Is potassium sulfide an acid or base?

Synthesis and reactions In the laboratory, pure K2S may be prepared by the reaction of potassium and sulfur in anhydrous ammonia. Sulfide is highly basic, consequently K2S completely and irreversibly hydrolyzes in water according to the following equation: K2S + H2O → KOH + KSH.

Is potassium sulfide a precipitate?

Silver nitrate, AgNO3 , and potassium sulfide, K2S , are soluble ionic compounds, which means that they dissociate completely in aqueous solution to form cations and anions. When these two aqueous solutions are mixed, silver sulfide, Ag2S , an insoluble ionic compound that precipitates out of solution, will be formed.
