Question

What else is produced during the replacement reaction of magnesium and hydrochloric acid?

Answer 1

Answer: Magnesium Chloride $(MgCl_2)$ is produced other than hydrogen gas in the following reaction.

Explanation:

The given reaction is a type of single displacement reaction. This reaction is defined as the reaction in which a more reactive metal displaces a less reactive metal in a chemical reaction.

For the reaction of magnesium and hydrochloric acid, magnesium metal is more reactive than hydrogen, so it will easily displace hydrogen from its chemical reaction.

The equation follows:

$Mg(s)+2HCl(aq)\rightarrow MgCl_2(aq)+H_2(g)$

By Stoichiometry,

1 mole of magnesium metal reacts with 2 moles of hydrochloric acid to produce 1 mole of magnesium chloride and hydrogen gas.

Hence, the other product formed in the given reaction is magnesium chloride.

Answer 2

Mg+ 2HCl ➡️ H2+ MgCl2
