The aim of this activity is for students to understand simple formulae and write word equations. Experiments show how to make soluble salts by two different methods and the construction of the associated word equations are demonstrated.

This item teaches:

• about the formation of soluble salts by reacting acids with alkalis
• about the formation of soluble salts by reacting acids with certain metals
• about the formation of soluble salts by reacting acids with insoluble bases
• about the use of word equations to describe chemical reactions
