The Concept of Qualitative Analysis
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.
