Question

What happens when iron fillings are added to dilute hydrochloric acid?

• A. Hydrogen gas and Iron chloride are produced.
• B. Chlorine gas and Iron hydroxide are produced.
• C. NO reaction takes place
• D. Iron salt and water are produced.

Answer 1

The correct option is A

Hydrogen gas and Iron chloride are produced.

When iron fillings are added to dilute hydrochloric acid, Iron displaces hydrogen from its chloride because it is more reactive than hydrogen.
The following displacement reaction occurs:
Fe(s) + 2HCl(aq) $\to$------> $FeC{l}_2$(aq) + $H_2$(g)
So, Hydrogen gas and Iron (II) chloride are produced.
