Learn that insoluble salts can be made by mixing appropriate ions, and that reacting acids with certain metals or bases will produce soluble salts. See this by mixing several pairs of chemicals and observing the results.

This item teaches:

• about the characteristics of salts
• about the formation of soluble salts by reacting acids with certain metals
• about the formation of insoluble salts by mixing solutions of certain ions
• about the formation of soluble salts by reacting acids with alkalis
• about the formation of soluble salts by reacting acids with insoluble bases
