The decomposition of water into hydrogen and oxygen when electric current is passed through it is which type of reaction?

Answer and explanation

Correct answer: Electrolytic decomposition reaction

When electric current is passed through water, it decomposes into hydrogen and oxygen: \(2H_2O \rightarrow 2H_2 + O_2\). The breakdown of a compound using electrical energy is called an electrolytic decomposition reaction, so option A is correct. In thermal decomposition, the compound breaks down due to heating; here, electrical energy causes the decomposition.
