Question
Write a word equation and then a balanced equation for the reaction taking place when:
Dilute hydrochloric acid reacts with iron filings.
Solution 1
- \[\ce{Iron filings + Hydrochloric acid (dil{.}) -> Iron (II) chloride + Hydrogen}\]
- \[\ce{Fe_{(s)} + 2HCl(dil{.}) -> FeCl2_{(aq)} + H2_{(g)}}\]
Solution 2
- \[\ce{Hydrochloric acid + Iron -> Iron(III) chloride + Hydrogen}\]
- \[\ce{6HCl_{(aq)} + 2Fe_{(s)} −> 2FeCl3_{(aq)} + 3H2_{(g)}}\]
