Question
What happens when iron filings are added to dilute hydrochloric acid?
Answer: Option C
:
C
In an aqueous solution, the hydrochloric acid dissociates to render hydronium ions and chloride ions. The released chloride ions oxidize the iron atoms to form iron (III) chloride as Fe3+ ions are more stable thanFe2+ ions. The hydrogen ions are reduced to hydrogen gas. Here, the reduction is observed in terms of the gain of electrons and the oxidation is observed in terms of the loss of electrons.Hence,hydrogen gas and iron (III) chloride are produced.
