| ChemSpider ID | 142491 <2> |
| EC Number | 215-197-0 <1> |
Complace and Synthesis
Potassium sulfide deserve to be ready by initially dealing with potassium hydroxide to excess hydrogen sulfide to form potassium hydrosulfide (KHS). Further therapy of KHS through the very same amount of potassium hydroxide geneprices potassium sulfide <9>.
KOH + H2S = KHS + H2O

Is It Dangerous
It might reason a fire hazard, so prealerts should be taken not to carry it in call through air. In the form of powder or dust, it is explosive. Ingestion, inhalation and also skin contact may cause severe injury and even fatality. It also harmtotally affects the eyes and also skin resulting in eye damages and skin burns. Hence all contact have to be avoided. It emits toxic fumes if heated to decomplace <4>. It is of a corrosive nature and poisonous for the environment <8>.
