Name the products formed when iron filings are heated with dilute hydrochloric acid
(a) Fe (III) chloride and water
(b) Fe (II) chloride and water
(c) Fe (II) chloride and hydrogen gas
(d) Fe (III) chloride and hydrogen gas
Answer: (d) Fe (III) chloride and hydrogen gas are formed when iron filings are heated with dilute hydrochloric acid. The Reason is 2Fe + 6HCl → 2FeCl3 (Iron (III) chloride) + 3H2.
