Introduction

Magnesium is a highly reactive metal that readily reacts with various substances, including acids. In this article, we will delve into the reaction between magnesium metal and aqueous sulfuric acid, resulting in the release of hydrogen gas and the formation of an aqueous solution of magnesium sulfate.

Chemical Reaction

The chemical reaction between magnesium metal and aqueous sulfuric acid can be represented by the following equation:

${ \text{Mg}(\text{s}) + \text{H}_2\text{SO}_{4(\text{aq})} \rightarrow \text{H}_{2(\text{g})} + \text{MgSO}_{4(\text{aq})} }$

In this reaction, magnesium metal (Mg) reacts with aqueous sulfuric acid (H2SO4) to produce hydrogen gas (H2) and an aqueous solution of magnesium sulfate (MgSO4).

Reactivity of Magnesium Metal

Magnesium metal is highly reactive due to its low ionization energy and high reactivity with acids. When magnesium metal comes into contact with aqueous sulfuric acid, it readily loses two electrons to form a magnesium ion (Mg2+). This process is known as oxidation.

Oxidation of Magnesium Metal

The oxidation of magnesium metal can be represented by the following equation:

${ \text{Mg}(\text{s}) \rightarrow \text{Mg}^{2+}(\text{aq}) + 2\text{e}^{-} }$

In this equation, magnesium metal loses two electrons to form a magnesium ion.

Reduction of Sulfuric Acid

The reduction of sulfuric acid occurs when the hydrogen ions (H+) in the acid gain electrons to form hydrogen gas. This process is known as reduction.

Reduction of Sulfuric Acid Equation

The reduction of sulfuric acid can be represented by the following equation:

${ 2\text{H}^{+}(\text{aq}) + 2\text{e}^{-} \rightarrow \text{H}_{2(\text{g})} }$

In this equation, two hydrogen ions gain two electrons to form one molecule of hydrogen gas.

Formation of Magnesium Sulfate

The formation of magnesium sulfate occurs when the magnesium ion (Mg2+) reacts with the sulfate ion (SO42-) to form a magnesium sulfate complex.

Magnesium Sulfate Equation

The formation of magnesium sulfate can be represented by the following equation:

${ \text{Mg}^{2+}(\text{aq}) + \text{SO}_{4}^{2-}(\text{aq}) \rightarrow \text{MgSO}_{4}(\text{aq}) }$

In this equation, the magnesium ion reacts with the sulfate ion to form a magnesium sulfate complex.

Conclusion

In conclusion, the reaction between magnesium metal and aqueous sulfuric acid results in the release of hydrogen gas and the formation of an aqueous solution of magnesium sulfate. The reactivity of magnesium metal is due to its low ionization energy and high reactivity with acids. The oxidation of magnesium metal and the reduction of sulfuric acid are two key processes that occur during this reaction.
