On what basis is the main difference between electrolytic decomposition and photolytic decomposition identified?
Answer and explanation
Correct answer: By the source of energy
Decomposition means breaking one compound into simpler substances, but the energy supplied can differ. In electrolytic decomposition, electrical energy drives the reaction, as in the electrolysis of water. In photolytic decomposition, light energy causes the compound to split, as in the decomposition of silver chloride in sunlight. Thus the source of energy is the distinguishing basis; precipitate colour, metal lustre, and gas mass are not defining criteria.
