Question

Name the gas evolved when magnesium reacts with dilute hydrochloric acid

Answer 1

When magnesium reacts with dilute hydrochloric acid hydrogen gas is released.

What is the chemical reaction between magnesium and hydrochloric acid?

• The chemical reaction between magnesium and hydrochloric acid is given below.
• In this equation, we can see that magnesium reacts with two molecules of hydrochloric acid.
• Mg + 2HCl ---------> MgCl2 + H2
• As a result of this reaction, salt of magnesium chloride and hydrogen gas are produced.
• MgCl2 is an anhydrous compound and it contains only 25% of magnesium.
• The salt of magnesium is highly soluble if aqua solution.
• This magnesium salt is used as a supplement to make up for the deficiency of Mg in blood.
