Chemical analysis is important for checking that the environment remains healthy and safe. If pollution occurs it can be detected and monitored by chemists using a variety of techniques.

There are two types of chemical analysis:

• Qualitative analysis - used to find out if a substance is present in a sample. An example of this type of analysis is the flame test.
• Quantitative analysis - used to find out how much of a substance is in a sample. These tests produce numbers in their results. An example of this type of analysis is a titration.
