it has a variable composition, & it retains properties of it's components
colloid
a heterogeneous mixture in which one component is dispersed as very fine particles in another component so distinct phases are difficult to see
Cohesion
the intermolecular attraction between like-molecules
the essential difference between a solution and a colloid is one of:
particle size
homogeneous mixture
one with NO boundaries separating its components
heterogeneous mixture
has two or more phases
the solvent ________ the solute
the solvent DISSOLVES the solute; usually the solvent is the most abundant component of a given solution
miscible
when the substances in a solution are miscible, both can dissolve each other no matter what the proportion; this means that it might not be meaningful to name one the solvent and one the solute
