When electric current is passed through water, it decomposes into hydrogen and oxygen. What type of reaction is this?
Answer and explanation
Correct answer: Electrolytic decomposition reaction
The decomposition of water by electric current is represented by \(2H_2O \xrightarrow{\text{electric current}} 2H_2 + O_2\). A decomposition reaction caused by electrical energy is called an electrolytic decomposition reaction, so option A is correct. Thermal decomposition requires heat, whereas photolytic decomposition requires light energy.
