In this unit, students will investigate reactions of acids. Students will review the pH scale for measuring 'degrees of acidity', which will lead to a discussion of the characteristics of acids, bases and salts. Tests for gases, acids and alkalis will also be taught through a series of practical activities. The unit will provide opportunities to collect and record data in tables and for graph plotting. Students will use word equations to describe chemical reactions. They will look for patterns in reactivity in order to deduce reagents needed or products formed.
