,4.1 Ionic Compounds in Aqueous
Solution
§ Objectives:
• Define solvent and solute
• Describe the behavior of strong
electrolytes, weak electrolytes and
nonelectrolytes in water
• Predict the solubility of common ionic
substances in water
• Predict products of chemical reactions
upon mixing solutions of ionic
compounds
• Write net ionic equations

§ Solvent: compound that has the same
physical state as the solution - frequently
a liquid.
§ Solute: substance being dissolved.
§ Aqueous solution: water is the solvent.

§ Strong electrolyte: compound that
separates completely into ions in
water.
§ Weak electrolyte: molecule that only
partially ionizes when dissolved in
water. acid
• Ionization is the separation of a molecular
compound into individual cations and
anions when dissolved in water. 198
