Magnesium Sulfide Structure
Magnesium sulfide reacts v water forming hydrogen sulfide and magnesium hydroxide <5>.
MgS + 2H2O = H2S + Mg(OH)2
It reacts through phosphoric mountain to give magnesium phosphate and also hydrogen sulfide <7>.
3MgS + 2H3PO4 = Mg3(PO4)2 + 3H2S
Magnesium sulfide reacts with hydrochloric mountain to create 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 straight semiconductor, the finds applications as a blue-green emitter and photodetector for ultraviolet light of quick wavelength <4>.As a lab reagent <10>.

Is the Dangerous
It may catch fire if huge quantities space self-heated. MgS is acutely toxic as soon as swallowed or lugged in call with skin and eyes leading to eye damage. It is corrosive and very harmful to aquatic life. The compound is hazardous as soon as it come in contact with moisture producing poisonous hydrogen sulfide gas <1, 4>.
