Best Answer

The chemical reaction for Magnesium (Mg) in Sulfuric acid (H2SO4) is given by the equation:

Mg + H2SO4 ---> MgSO4 + H2 gas.

The products of this reaction are Magnesium Sulfate (MgSO4, a salt) and elemental Hydrogen (H2, a gas), as shown in the equation.

Single Displacement (the Mg displaces the Hydrogen)

If you want to get a little more complicated, this is an acid-metal reaction (because acids will react/corrode metals in a single displacement reaction to create hydrogen gas.)

The main observations are, 1-pungent smell of HCl gas and 2- the emitted gas gives white fumes with NH3.

MgCl2 + H2SO4 ------> MgSO4 + 2HCl

HCl + NH3 ------> NH4Cl(white fumes)
