Question

What else is produced during the replacement reaction of magnesium and hydrochloric acid? Mg 2HCl → H2.

Answer 1

A reaction in which the chemical element of the reactant is replaced by another to produce a product is called a single replacement reaction.

In a reaction, a hydrogen, metal or halogen element can get replaced with other more reactive elements to yield products.

The reaction of magnesium and hydrochloric produces:

$\rm MgCl_{2}$

The reaction can be explained as:

• The reaction between the  $\rm Mg$  and $\rm HCl$ is a single displacement reaction in which the more reactive metal replaces the less reactive metal from the compound.

• Magnesium metal is more reactive compared to hydrogen and hence replaces $\rm H_{2}$ from chlorine to produce:

$\rm Mg (s) + 2 \;HCl \;(aq) \rightarrow MgCl_{2} \;(aq) + H_{2} (g)$

Therefore, another product formed will be magnesium chloride.
