Document Summary

Aqueous solution- solutions in which water is the dissolving medium or solvent. Because the oxygen atom has a greater attraction for electrons, the shared electrons tend to spend more time close to the oxygen than to either of the hydrogens. The extent to which a solution can conduct an electric current depends directly on the number of ions present.

Hydrochloric acid, nitric acid, and sulfuric acid are aqueous solutions and should be written in chemical equations as. Hcl (aq), hno3 (aq), and h2so4 (aq), respectively, although they often appear without the (aq) A strong acid is one that completely dissociates into its ions. Thus, if 100 molecules of hcl are dissolved in h2o, 100 h+ ions and 100 cl- ions are produced. Virtually no hcl molecules exist in aqueous solution.
