Document Summary

An aqueous solution is a homogenous mixture of water (the solvent) with another substance (the solute). We often express the concentration of a solution in molarity, the number of moles of solute per liter of solution. Solutes that completely dissociate (or completely ionize in the case of the acids) to ions in solution are strong electrolytes and are good conductors of electricity. Water soluble ionic compounds, strong acids and strong bases are strong electrolytes. Solutes that only partially dissociate (or partially ionize) are weak electrolytes. Solutes that do not dissociate (or ionize) are nonelectrolytes. A substance that dissolves in water to form a solution is soluble. The solubility rules are an empirical set of guidelines that help predict the solubilities of ionic compounds; these rules are especially useful when determining whether or not a precipitate will form. In a precipitation reaction, we mix two aqueous solutions and a solid a.
