Question
Give one example of a decomposition reaction which is carried out with electricity.
Advertisements
Solution
When an electric current is passed through acidified water, it decomposes to give hydrogen gas and oxygen gas. This reaction can be represented as:
\[\ce{\underset{Water}{2H2O_{(l)}} ->[Electricity][(Decomposition)] \underset{Hydrogen}{2H2_{(g)}} + \underset{Oxygen}{O2_{(g)}}}\]
