Chapter 4: Aqueous Reactions and Solution Stoichiometry Chapter Summary Introduction and Section 4.1  Solutions in which water is the dissolving medium are called  aqueous solutions . The  component of the solution that is in the greater quantity is the  solvent . The other components are  solutes . Any substance whose aqueous solution contains ions is called an  electrolyte . Any substance that forms a solution  containing no ions is a  nonelectrolyte . Those electrolytes that are present in solution entirely as ions are  strong  electrolytes , whereas those that are present partly as ions and partly as molecules are  weak electrolytes . Ionic  compounds dissociate into ions when they dissolve, and they are strong electrolytes. The solubility of ionic  substances is made possible by  solvation , the interaction of ions with polar solvent molecules. Most molecular  compounds are nonelectrolytes, although some are weak electrolytes and a few are strong electrolytes. When  representing the ionization of a weak electrolyte in solution, a double arrow is used, indicating that the forward and  reverse reactions can achieve a chemical balance called a  chemical equilibrium .
