8/10/09 3 Solution Composition Solution: A homogeneous mixture Solvent: Solute: The major component The minor component The solute and solvent can be any combination of solid ( s ), liquid ( l ), and gaseous ( g ) phases. Dissolution: Two (or more) substances spread out, or disperse, into each other at the level of individual atoms, molecules, or ions.
