oxidize

Of course, this causes the nail clippers to oxidize and the water turns rusty, but it boils.

They oxidize organic materials, changing them to compounds that can be absorbed by plants and used in building protoplasm.

My purpose in slackening my heat as soon as the pig-iron was melted was to oxidize the phosphorus and sulphur ahead of the carbon.

The purpose now is to oxidize the carbon, too, without reducing the phosphorus and sulphur and causing them to return to the iron.

Just as alcohol vaporizes at a lower heat than water, so sulphur and phosphorus oxidize at a lower heat than carbon.

Chromic and nitric acids oxidize it to oxalic acid and carbon dioxide.
