Content

Getting

Passing hydrogen sulfide through an acidic solution of polonium (II) salt.

{\mathsf {PoCl_{2}+H_{2}S\ {\xrightarrow {}}\ PoS\downarrow +2HCl}}

{\ displaystyle {\ mathsf {PoCl_ {2} + H_ {2} S \ {\ xrightarrow {}} \ PoS \ downarrow + 2HCl}}}

Physical Properties

Polonium sulfide forms black crystals.

Not soluble in water, p PR = 28.26, and ethanol .

Chemical Properties

Decomposes on heating:
