What is the observation when H2SO4 reacts with MgCl2?

Answer 1

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.

Answer 2

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.)

Answer 3

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)

Answer 4

When sulfuric acid (H2SO4) reacts with magnesium chloride (MgCl2), a double displacement reaction occurs, leading to the formation of magnesium sulfate (MgSO4) and hydrochloric acid (HCl) as products. This reaction is often used in the laboratory to demonstrate double displacement reactions and the formation of new compounds.

Answer 5

Yes: The reaction equation is H2SO4 + Mg -> MgSO4 + H2 (gas)

Answer 6

Mg(s) + 2H2O(l) -> Mg(OH)2(aq) + H2(g)
