What happens if you remove oxygen from water?
Water is one third oxygen; without it, the hydrogen turns into gaseous state and expands in volume. The oceans would evaporate and bleed into space. As oxygen disappears from the oceans’ water, the hydrogen component becomes an unbound free gas.
Can boiled water go bad?

Is it OK to reboil water for tea?
“You need freshly drawn water for a good cup because reboiling it takes out all the oxygen and nitrogen out of it.” If your cup of tea does go cold halfway through drinking it, Gorman is a strong advocate of microwaving it for 15-20 seconds instead of making a new one.
Does boiling water get rid of chlorine?
Does Boiling Water Remove Chlorine? Yes, boiling water for 15 minutes is one way to release all the chlorine from tap water. At room temperature, chlorine gas weighs less than air and will naturally evaporate off without boiling. But heating up the water to a boil speeds up the removal process.
Why does my boiled water taste like metal?
