Can you say this in Spanish?
In Spanish how would you say the word catalyst, as such a catalyst is a chemical change that occurs when a substance changes something else but it does not change itself.

Catalizador is the most used.
Edit: I must correct myself, because a catalizador is a susbtance that can increase the speed of a reaction, not a chemical change. So, the word that you are looking for is catálisis.
