Magnesium Sulfide Structure

Prominent Reactions

Magnesium sulfide reacts v water creating hydrogen sulfide and also magnesium hydroxide <5>.

MgS + 2H2O = H2S + Mg(OH)2

It reacts through phosphoric acid to provide magnesium phosphate and hydrogen sulfide <7>.

3MgS + 2H3PO4 = Mg3(PO4)2 + 3H2S

Magnesium sulfide reacts v hydrochloric acid to develop magnesium chloride and hydrogen sulfide <8>.

MgS + 2HCl = MgCl2 + H2S

It reacts with nitric acid offering magnesium nitrate and hydrogen sulfide <9>.

MgS + 2HNO3 = Mg(NO3)2 + H2S

Magnesium Sulfide (MgS) Uses

Is the Dangerous

It may record fire if big quantities space self-heated. MgS is acutely toxic when swallowed or carried in call with skin and eyes causing eye damage. That is corrosive and very harmful to aquatic life. The link is hazardous once it come in contact with moisture developing poisonous hydrogen sulfide gas <1, 4>.
