MIXTURES are separated into 3 categories into 3 categories based on particle size:
1) Solutions - contain a SOLUTE & SOLVENT, are evenly mixed and homogenous
NOTE: a solution of metals is called an ALLOY.
2) Suspensions - heterogenous, has the largest particle size which can be filtered
3) Colloids - heterogenous, particles can scatter light, do not settle out, & particles cannot be separated by filtering.
