The qualitative analysis of simple inorganic compounds involves detection and confirmation of cationic and anionic species (basic and acidic radical) in them.
1. Qualitative analysis deals with the detection of the presence or absence of elements in compounds and of chemical compounds in mixtures.
2. Quantitative analysis deals with the determination of the...
Classical qualitative analysis method includes separation and identification of compounds.
Separations may be done by methods such as precipitation, extraction and distillation.
Identification may be based on differences in colour, odour, melting...
The majority of organic compounds are composed of a relatively small number of elements.
The most important ones are: carbon, hydrogen, oxygen, nitrogen, sulphur, halogen, phosphorus.
Elementary qualitative analysis is concerned with...
a) Controlling
(b) Measurement of actual performance
Once performance standards are set, the next step is measurement of actual performance. Performance should be measured in an objective and reliable manner. There are...
