Cards Term dissociation Definition separation of ions that occur when an ionic compound dissolves Term net ionic equation Definition only those compounds and ions that undergo a chemical change in a reaction in an aqueous solution Term spectator ions Definition ions that do not take part in a chemical reaction and are found in solution both before and after the reaction Term Ionization Definition ions formed from solute molecules by the action of the solvent in the process Term hydronium ion Definition the H3O+ ion Term strong electrolyte Definition any compound whose dilute aqueous solutions conduct electricity well; this is due to the presence of all or almost all of the dissolved compound in the form of ions Term weak electrolyte Definition any compound whose dilute aqueous solutions conduct electricity poorly; this is due to the presence of a small amount of the dissolved compuond in the form of ions Term colligative properties Definition properyies that depend on the concentration of solute particles but not on their identity Term volatile susbstance Definition one that has little tendency to become gas under existing conditions Term molal freezing-point constant Definition the freezing-point depression of the solvent in a 1-molal solution of a nonvolatile, nonelectrolyte solute Term freezing-point depression Definition difference between the freezing points of the pure solvent and a solution of a nonelectrolyte in that solvent, abd it is directly proportional to the molal concentration of the solution Term molal boiling-point constant Definition boiling-point elevation of the solvent ina 1-molal solution of a nonvolatile, nonelectrolyte soulte Term boiling-point elevation Definition difference between the boiling points of the pure solvent and a nonelectrolyte solution of the solvent, and it is directly proportional to the molal concentration of the solution Term semipermeable membranes Definition allow the movement of some particles while blocking the movementof others Term osmosis Definition movement of solvent through a semipermeable membrane from the side of lower solute concentration to the side of higher concentration
