SOLUTIONS: Are homogeneous mixtures.
SOLVENT: The chemical in bigger proportion.
SOLUTE: The chemical in lower proportion.
We will concentrate our attention in the AQUEOUS SOLUTIONS since these are the ones that we use in the chemistry lab most of the time. Aqueous solutions are the ones in which the solvent is water. We can also find ALCOHOLIC SOLUTIONS, where the solvent is alcohol.
ELECTROLYTES: If the solute liberates ions in solution, (Ionic compounds that separate in their ions or acids that release hydrogen ions in solution) those ions will allow the solution to conduct electricity. These substances are called electrolytes
