Learning outcomes Success criteriaUnderstand what bases are. State the definition for a base.

Name the three types of base.

Given its name, you can classify a substance as a base or not.

Bases

• A base is a substance which reacts with an acid to produce water.

• The three types of base are:– metal oxides– metal hydroxides– metal carbonates
