Magnesium Sulfide Structure
Prominent Reactions
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) Uses
