- Chocolate.
- Beer.
- Cold Cuts.

This is the reason why stocks of compressed gas cylinders are usually stored separately from the main lab and are treated with caution.
How are oxidizing agents used in oxidation reduction?
Oxidizing agents are used for removing an electron from another substrate – hence they are known to be involved in an oxidation-reduction reaction. As they usually transfer oxygen to another chemical substance, they can provide oxygen to flammable materials that can burn when used in the lab.
