Study Notes
Qualitative Analysis
- The purpose of qualitative analysis is to identify the constituents of a substance, typically an inorganic salt.
Formation of a Salt
- The part contributed by the base in the formation of a salt is called the anion.
Analytical Techniques
- Macro analysis involves the use of a relatively large amount of substance, typically in the range of 0.1-1 gram.
- Micro analysis, on the other hand, requires a much smaller amount of substance, typically in the range of 1-100 milligrams.
Qualitative Analysis Procedures
- Systematic analysis of an inorganic salt involves the identification of both anions and cations present in the salt.
- Qualitative analysis typically involves easily perceptible reactions, such as color changes, precipitation, and gas evolution.
Nature of Qualitative Analysis
- Qualitative analysis is a non-quantitative analytical technique, meaning it does not provide information about the amount of substance present, but rather its composition.
Test your knowledge on the systematic qualitative analysis of inorganic salts, including the identification of cations and anions present in the salt or a mixture of salts. Explore the process of qualitative analysis and the nature of substances.
