Substance is a general term roughly equivalent to "matter". Mixture has a specific meaning.


"Substance" is a general term that is roughly identical to "matter" - it could relate to anything - an element, a mixture or a chemical compound.

"Mixture" on the other hand specifically relates to two or more "substances" that are physically mixed together so that there is a roughly uniform distribution of one in the other, but no chemical reaction takes place.
