What does Hydrogenation mean? GCSE Core Chemistry?

Is it the same/similar to hydration?
it's to do with hardening a fat, so at room temperature it's not liquid
Oooo, thanks!

Hydrogenation is hardening a fat so reacting it with hydrogen at about 60 degrees Celsius in the presence of a nickel catalyst.

it is not necessarily harderning a fat. I do CIE IGCSE Chemistry and what it is is basically adding hydrogen to something (could be a fat) in the presence of Ni(s) and at 60 degrees. It can also be used to convert and alkene into an alkane for example you could convert C2H4 to C2H6 (Ethene to Ethane) using hydrogenation.

Hydration is basically addding water to something so dont get the 2 mixed up

Hydrogenation is literally adding hydrogen (H2) to a species. This could be adding hydrogen to reduce nitriles to amines or reduce alkenes to alkanes. This can be done in various ways, some methods involving a catalyst (Nickel is commonly used) and some methods that do not involve a catalyst.
It's basically called hardening and it's reacting unsaturated oils with hydrogen gas to open the double carbon = carbon bonds up. You do it at 60 degrees celsius and with a nickel catalyst. It raises the melting point so it doesn't melt at room temp. the treated oil is called a hydrogenated oil
