quantitative chemical analysis, branch of chemistry that deals with the determination of the amount or percentage of one or more constituents of a sample. A variety of methods is employed for quantitative analyses, which for convenience may be broadly classified as chemical or physical, depending ...
qualitative models of bonding are discussed, with particular attention given to the formation of ionic and covalent bonds and thecorrelationof the latter with molecular shapes. The more-sophisticated quantum mechanical approaches to bond formation are then described, followed by a survey of a number ...
There are several types of analytical techniques used depending on the nature of the compound being analyzed and the goals of the analysis. The analytical techniques are divided into wet chemistry and instrumental methods. Wet chemistry involves the qualitative analysis of samples based on observations...
From the inception of Lewis' theory of chemical bonding, hypervalency has remained a point of difficulty that has not been fully resolved by the currently accepted qualitative definition of this term. Therefore, in this work, a quantitative measure of hypervalency has been developed. The only req...
Quantitative research is the opposite ofqualitative research, which involves collecting and analyzing non-numerical data (e.g., text, video, or audio). Quantitative research is widely used in the natural and social sciences: biology, chemistry, psychology, economics, sociology, marketing, etc. ...
Analytical chemistry definition: the subdivision of chemistry dealing with the qualitative and quantitative determination of chemical components of substances.. See examples of ANALYTICAL CHEMISTRY used in a sentence.
Chemistry. the analysis of a substance to determine the amounts and proportions of its chemical constituents. Compare qualitative analysis. Statistics. the use of mathematical analysis, especially computerized, to better understand variable components in a system, as in business forecasts or investment...
Analytical chemistry makes use ofstandardsand error analysis. Qualitative and Quantitative Analysis Qualitative analysischaracterizes the identity of a specimen, while quantitative analysis examines its mass or concentration. Techniques used in qualitative analysis include chemical tests, spectroscopy, spectrometry...
