# Oxyhydrogen Oxyhydrogen is the stoichiometric mixture of [[Hydrogen]] and [[Oxygen]] gas — two parts to one, exactly the ratio [[Electrolysis]] of [[Water]] produces and exactly the ratio [[Combustion]] consumes. It is the reaction canon in its most literal form: the products of splitting water, held together in the proportion that recombines to make it again. ## A closed loop with a sharp edge The mixture is its own complete fuel and oxidiser, so it needs nothing from the air and burns at a temperature high enough for welding and for lamp work. It is also detonable across an unusually wide composition range, which is why it is generated on demand rather than stored — the safety logic behind [[Hydrogen_production]] practice generally. The round trip splitting with [[Electrolysis]] and recombining in a [[Fuel_cell]] or a flame is the storage cycle the [[PORTAL_Energy|energy]] branch of this spine is built around, and its losses at each step are what [[Energy_transformation|conversion efficiency]] arguments are really about. **Reads with:** *General Chemistry: Principles, Patterns, and Applications (2011)* — [OTL record](https://open.umn.edu/opentextbooks/textbooks/general-chemistry-principles-patterns-and-applications) · [download](https://www.saylor.org/site/textbooks/General%20Chemistry%20Principles,%20Patterns,%20and%20Applications.pdf).
