Document Summary

Email name and section to find exam scores. *aqueous solutions are among the most common solution type. Consider ionic compounds (solute) dissolving in water (solvent) Ionic compound dissociates into (+) and (-) ions. Polyatomic ions stay together as one group when dissolving. A substance that conducts electricity when dissolved in water. Dissociate into ions (charged species) in aqueous solution. Molecules become solvated but no ions are formed. Many (but not all) molecular compounds are nonelectrolytes. Most soluble covalent compounds do not dissociate in water. Ethanol dissolves in water, but does not dissociate into ions. Identify the major ionic species present in an aqueous solution of caco3. Identify the species present in an aqueous solution of c3h8o. C3h8o is a molecular compound that does not dissociate. Compounds containing the following ions are generally soluble. Exceptions (when combined with ions on the left the compound is insoluble) Compounds containing the following ions are generally insoluble.
