Questions
Write chemical equation for the event.
Iron filings are dropped in aqueous solution of copper sulphate.
Iron dissolved in aqueous solution of copper sulphate.
Advertisements
Solution
Iron displaces copper from copper sulphate solution forming ferrous sulphate and copper.
\[\ce{\underset{\text{Iron}}{Fe_{(s)}} + \underset{\text{Copper sulphate}}{CuSO_{4(aq)}} -> \underset{\text{Ferrous sulphate}}{FeSO_{4(aq)}} + \underset{\text{Copper}}{Cu_{(s)}}}\]

Three metal samples of magnesium, aluminium and iron were taken and rubbed with sandpaper. These samples were then put separately in test tubes containing dilute hydrochloric acid. Thermometers were also suspended in each test tube so that their bulbs dipped in the acid. The rate of formation of bubbles was observed. The above activity was repeated with dilute nitric acid and the observations were recorded.
Answer the following questions:
(i) When the activity was done with dilute hydrochloric acid, then in which one of the test tubes was the rate of formation of bubbles the fastest and the thermometer showed the highest temperature?
(ii) Which metal did not react with dilute hydrochloric acid? Give reason.
(iii) Why is hydrogen gas not evolved when a metal reacts with dilute nitric acid? Name the ultimate products formed in the reaction.
