Chemists monitor our environment using a variety of quantitative and qualitative analysis techniques. The results from quantitative analysis are used in calculations that give essential information.
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.
