In which experiment does the volume ratio of the gases obtained indicate the composition of water?
Answer and explanation
Correct answer: Electrolysis of water
Electrolysis of water produces hydrogen and oxygen gases. The volume of hydrogen is twice the volume of oxygen, so their volume ratio is 2:1. This indicates the combining ratio of hydrogen and oxygen in water. In contrast, burning magnesium mainly forms magnesium oxide and does not produce gases in this ratio.
