Magnesium Sulfide Structure
Magnesium sulfide reacts v water creating hydrogen sulfide and also magnesium hydroxide <5>.
MgS + 2H2O = H2S + Mg(OH)2
It reacts with phosphoric mountain to offer magnesium phosphate and also hydrogen sulfide <7>.
3MgS + 2H3PO4 = Mg3(PO4)2 + 3H2S
Magnesium sulfide reacts through hydrochloric acid to develop magnesium chloride and also hydrogen sulfide <8>.
MgS + 2HCl = MgCl2 + H2S
It reacts v nitric acid giving magnesium nitrate and also hydrogen sulfide <9>.
MgS + 2HNO3 = Mg(NO3)2 + H2S
Magnesium Sulfide (MgS) UsesBeing a wide band-gap direct semiconductor, it finds application as a blue-green emitter and also photodetector because that ultraviolet irradiate of brief wavelength <4>.As a rap reagent <10>.

Is that Dangerous
It may capture fire if huge quantities are self-heated. MgS is acutely toxic once swallowed or lugged in call with skin and also eyes resulting in eye damage. It is corrosive and very harmful come aquatic life. The link is hazardous as soon as it come in call with moisture producing poisonous hydrogen sulfide gas <1, 4>.
