Hydrogen and oxygen are stored separately for safety reasons. When stored together, there is a risk of an explosive mixture forming, as hydrogen and oxygen can react vigorously and even explode when exposed to an ignition source.
Here are the primary reasons why hydrogen and oxygen should be stored separately:
Combustibility: Hydrogen is highly flammable, and oxygen supports combustion. When hydrogen and oxygen mix in the presence of an ignition source (such as a spark or flame), they can undergo a rapid and exothermic reaction, resulting in an explosion. By storing them separately, the likelihood of accidental mixing is minimized.
Safety: Separating hydrogen and oxygen reduces the risk of unintended reactions. Uncontrolled reactions between the two gases can lead to the release of large amounts of energy and can be hazardous in confined spaces or areas without proper safety measures.
Stability: Storing gases separately helps maintain their stability. Hydrogen and oxygen can react with impurities, catalysts, or certain materials, which could initiate or accelerate their reaction. By storing them in separate containers, the risk of accidental contact with substances that could catalyze their reaction is reduced.
It's important to note that storing and handling hydrogen and oxygen gases require proper precautions and adherence to safety guidelines to prevent accidents or incidents.
