Homogeneous Mixtures
Matter that is uniform throughoutReferred to as a Solution 1 visible part
(uniform distribution)
Constant composition
Even distribution of particles
Solution (Homogeneous Mixture) Examples
Salt water Brass
Glass Solutions appear to be one part, but are actually just mixed very well
