Oxygen gas produced by a Solid element + sodium hydroxide solution?

[BenDover]

TL;DR

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

In general, oxidation relases energy (e.g. burning produces heat), and reduction requires energy (e.g. electrolysis of water produces hydrogen and oxygen).

In general peroxides and superoxides often react with water producing oxygen. Not that they specifically require alkaline solution (they do produce hydroxides while reacting though).

 

[chemisttree]

There are no solid elements that will react with aqueous sodium hydroxide to produce oxygen.

@chemisttree, doesn't potassium perchlorate plus water produce potassium hydroxide plus oxygen?

 

[chemisttree]

Potassium perchlorate is not an element. It is a compound.

Oops, I didn't read carefully enough $-$ I'd have thought that fact would go without saying.

In general, what you need to produce oxygen from water is oxidants.
There is one free element oxidant consistently strong enough to react with water to produce oxygen, but it is gaseous at STP: fluorine. Chlorine is close, but also gaseous.
Strongest oxidizing element which is solid at STP is iodine, but it does not produce free oxygen in alkali solutions: it produces iodides and iodates.

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.

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.

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.
