Question
Write the chemical equation of the reaction which takes place when iron reacts with dilute sulphuric acid. What happens when the gas produced is ignited with a burning matchstick?
Solution
The chemical equation of the reaction between iron and dilute sulphuric acid is as follows:
Fe(s) + H2SO4(aq) → FeSO4(aq) + H2(g)
When the hydrogen gas produced is ignited with a burning matchstick, the gas burns with a 'pop' sound and a small explosion takes place.
