- TL;DR Summary
- Solid element + sodium hydroxide solution = oxygen gas
Hello. I am wondering; which solid at room temperature elements produce oxygen gas when put into a solution of sodium hydroxide?
Thanks
Thanks
In general, oxidation relases energy (e.g. burning produces heat), and reduction requires energy (e.g. electrolysis of water produces hydrogen and oxygen).BenDover said:Summary:: Solid element + sodium hydroxide solution = oxygen gas

The way I read it question is not about "producing oxygen from water" but about "producing oxygen in a reaction with water". If so, anything that decomposes in the presence of water producing oxygen fits.snorkack said:In general, what you need to produce oxygen from water is oxidants.
Yes, but the only element that can decompose to oxygen is, well, oxygen.Borek said:The way I read it question is not about "producing oxygen from water" but about "producing oxygen in a reaction with water". If so, anything that decomposes in the presence of water producing oxygen fits.
Water (with or without .1 M lye dissolved in it) can decompose into hydrogen and oxygen, but, as @chemisttree stated, oxygen is not released by introduction of a solid element to aqueous sodium hydroxide.snorkack said:Yes, but the only element that can decompose to oxygen is, well, oxygen.
It does have a second reasonably metastable allotropic form (ozone), but this is also a gas at STP.
When a solid element, such as magnesium or iron, is added to a solution of sodium hydroxide, a chemical reaction occurs. The solid element reacts with the sodium hydroxide to form a new compound, while also releasing oxygen gas as a byproduct.
Sodium hydroxide is a strong base that is commonly used in chemical reactions to facilitate the production of oxygen gas. It helps to break down the solid element and promote the release of oxygen gas.
The amount of oxygen gas produced is directly proportional to the amount of solid element used in the reaction. This means that the more solid element you use, the more oxygen gas will be produced.
No, the production of oxygen gas in this reaction is not spontaneous. It requires the addition of a solid element and sodium hydroxide solution, as well as a source of energy such as heat or light, to occur.
It is important to wear protective gear, such as gloves and goggles, when handling sodium hydroxide as it is a caustic substance. Additionally, the reaction may produce heat and gas, so it should be conducted in a well-ventilated area to avoid any potential hazards.
