Simple qualitative analysis involves the identification of the constituents of an inorganic substance or a mixture of substances. The inorganic substances are split-up into two types of charged particles one of which is positively charged and the other is negatively charged. The charged particles are called ions or radicals. The positively charged ions are called cation or basic radical. The negatively charged ion is called anion or acid radical. In the qualitative analysis of an inorganic

DISCUSSION: Qualitative analysis is used to determine the presence of cations or anions present within a sample and their impurities. Information known‚ such as chemical and physical properties‚ about cations and anions can be used to determine what steps should be used to separate the sample into one‚ specific ion. Qualitative analysis involves forming and decomposing complex ions. Qualitative tests are very sensitive‚ allowing to detect a very small amount present in sample. Due to sensitivity

Qualitative Methods And analysis * . Quantitative research is used widely in social sciences such as sociology‚ anthropology‚ and political science. Research in mathematical sciences such as physics is also ’quantitative’ by definition‚ though this use of the term differs in context. In the social sciences‚ the term relates to empirical methods‚ originating in both philosophical positivism and the history of statistics‚ which contrast qualitative research methods. Qualitative

categories of research methodologies‚ the quantitative and the qualitative‚ and they both are used to answer research questions but in different ways. The main distinctions between these approaches lie in foundational premises related to how human beings understand the nature of the world in a better way (Willis‚ 2007). The selection of the approach to be used will depend on the research problem to be analyzed.

An Introduction to Qualitative Analysis Purpose: Tests the ions of Mg2+‚ Ca2+‚ Sr2+‚ and Ba2+‚ and identify them separately. By using these observations‚ identify the unknown ion. Then tests the ions of SO42-‚ CO32-‚ Cl-‚ and I-‚identify them separately‚ and use the observation to identify the unknown.

Qualitative Analysis of Cations Short Overview The most common cations have been placed into five groups based upon solubility in aqueous solutions when different reagents are added. The reactions which occur are useful in identifying the presence of these cations in unknown samples. The process of identifying the cations is called qualitative analysis. The purpose of this experiment is to identify which cations are present in unknown solutions. A data sheet was not prepared for this experiment
