Steps to process neutralisation

• Once the level of acidity or alkalinity is known, we can choose an equal substance to neutralise it with.

• To neutralise a solution, you first need to know if it is acidic or alkali.

• A litmus paper test will tell you if a solution is acidic or alkali, but not by how much

• Use a universal indicator to tell you how strong or weak the solution is (pH number)

To name a salt we follow a simple rule:

1. Keep the name of the __________ present in the ____________

2. Add a modified version of the ___________ name to the end.

• metal, acids, alkali

• alkali, acids, metal

• metal, alkali, acids
