Does mixture of hydrogen and oxygen actually has to be ignited or the reaction occurs even without ignition when some critical H:O proportion is reached?
Borek said:In theory such mixture reacts even at room temperature, albeit very slowly.
SAZAR said:"The hydrogen autoignition temperature, the temperature of spontaneous ignition in air, is 500 °C (932 °F)."
SAZAR said:That high! ...I would have thought it's much lower. ...No way; that must be wrong. (?)
A mixture of hydrogen and oxygen is a combination of these two gases in varying proportions. It is not a compound, as the two gases do not chemically react with each other, but rather a physical mixture.
A mixture of hydrogen and oxygen has properties that depend on the proportions of each gas present. It can be colorless, odorless, and tasteless, and can exist in gaseous or liquid states. It is also highly flammable.
A mixture of hydrogen and oxygen can be created through various methods, such as electrolysis of water or the decomposition of certain compounds. It can also be created by separating the two gases in their liquid states and then mixing them together.
A mixture of hydrogen and oxygen has many industrial and scientific uses. It is commonly used in fuel cells to produce electricity, in welding and cutting processes, and in the production of fertilizers and other chemicals.
While hydrogen and oxygen are both relatively safe gases to handle individually, a mixture of the two can be highly explosive. It should be handled with caution and proper safety precautions should be taken to avoid accidents.
