Volume ratio of oxygen to hydrogen in electrolysis of water? In the experiment of electrolytic water, the gas volume in the negative scale tube connected to the power supply is _____, and the gas volume in the positive scale tube connected to the power supply is _____, and the ratio of them is about ______. Volume ratio of oxygen to hydrogen in electrolysis of water? In the experiment of electrolytic water, the volume of gas in the negative scale tube connected to the power supply is _____, and the volume of gas in the positive scale tube connected to the power supply is _____, the ratio of which is about ______.
By chemical equation:
2H2O (electrolysis)=2H2+O2. It can be seen that two moles of water electrolysis produces two moles of hydrogen at the positive electrode and one mole of oxygen at the negative electrode, so the volume ratio is two to one.
Mainly from the equation and judge that the negative electrode is oxidation reaction, the positive electrode is reduction reaction

What is the reason for the 2:1 volume ratio of hydrogen to oxygen produced in electrolytic water experiments? In the experiment of electrolytic water, if sodium hydroxide is added to the water, why is the volume ratio of hydrogen to oxygen greater than 2:1; soon it is about 2:1 What is the reason for the 2:1 volume ratio of hydrogen to oxygen produced in an electrolytic water experiment? In the experiment of electrolytic water, if sodium hydroxide is added to the water, why is the volume ratio of hydrogen to oxygen greater than 2:1; soon it is about 2:1
2H2O = energized =2H2+02. The ratio of hydrogen to oxygen produced is 2:1. The ratio of the amount of the substance is equal to the volume ratio of the substance, so the ratio of hydrogen to oxygen produced is 2:1
2H2O = energized =2H2+02. The ratio of generated hydrogen to oxygen is 2:1. The ratio of the amount of the substance is equal to the volume ratio of the substance, so the ratio of generated hydrogen to oxygen is 2:1
