Magnesium sulfide reacts with water forming hydrogen sulfide and magnesium hydroxide . It reacts with phosphoric acid to give magnesium phosphate and hydrogen sulfide. Magnesium sulfide reacts with hydrochloric acid to produce magnesium chloride and hydrogen sulfide.
What is the reaction between magnesium and Sulphur?
In magnesium sulfide (MgS), magnesium loses two electrons . Therefore, magnesium becomes a cation with a positive-two charge. Likewise, sulfur obtains the two electrons lost from magnesium. Thus, sulfur becomes an anion with a negative-two charge.

Is magnesium sulfide A mixture or pure substance?
A teaspoon of magnesium filings and a teaspoon of powdered sulfur placed together in a metal beaker is a mixture (combination of pure substances). The magnesium filings and sulfur that react with each other, forming magnesium sulfide is no longer a mixture because they underwent a chemical reaction.
What is magnesium sulfide used for?
It is used as a semiconductor . MgS (formula of magnesium sulfide) is a wide band-gap direct semiconductor. It produces a blue-green emitter. Because of this wide-bandgap property, magnesium sulphide can be used as a photodetector for the short wavelength of ultraviolet light.
Is magnesium sulfide flammable?
Reacts with water producing toxic and extremely flammable gas ; An irritant; [Alfa Aesar MSDS] See “Potassium sulfide.” See “Magnesium” and “Hydrogen sulfide.”
What type of structure does magnesium sulfide have?
| Names | Melting point 2,000 °C (3,630 °F; 2,270 K) approx. | Solubility in water decomposes | Structure | Crystal structure Halite (cubic), cF8 |

Is magnesium sulfide harmful?
MgS is acutely toxic when swallowed or brought in contact with skin and eyes leading to eye damage. It is corrosive and very harmful to aquatic life. The compound is hazardous when it comes in contact with moisture producing poisonous hydrogen sulfide gas [ 1 , 4 ] .
Does magnesium sulfide dissolve in water?
The sulfides of all metals except barium, calcium, magnesium, sodium, potassium, and ammonium are insoluble in water. BaS, CaS, and MgS are sparingly soluble .
Is magnesium a fluoride?
Magnesium fluoride is an inorganic compound with the formula MgF 2 . The compound is a white crystalline salt and is transparent over a wide range of wavelengths, with commercial uses in optics that are also used in space telescopes. It occurs naturally as the rare mineral sellaite.
