The Meaning of Qualitative Analysis
Explain the meaning of qualitative analysis
Qualitative analysis involves determining metals and non metals (or metallic and non-metallic elements) present in a given sample. It is a process used to determine what elements (or radicals) are present in the sample.
Whereas quantitative analysis involves determining how much (quantity) of a substance is present in a sample, qualitative analysis involves
identifying what (quality) substances are present in a sample.
Qualitative analysis may be divided into examination of:
- acidic or non-metallic radicals or negative ions;
- basic or metallic radicals, including ammonium ion.

analysis has numerous applications. The following are some applications
(importance) of qualitative analysis in real life.
Qualitative analysis techniques
is very important to be very keen when performing qualitative analysis
tests. Just a small error can cause misinterpretation of the contents of
a tested sample. The following are few but important measures that
should be observed when carrying out qualitative analysis experiments.
