Qualitative analysis chemistry

Qualitative Analysis is a fancy name for identifying the components of a compound or mixture using a series of tests. We use the qualities..

A short introduction of analytical chemistry and its main branches (qualitative and quantitative analysis) is given in this post. It includes topics such as acid-base equilibria, atomic absorption, calibration, environmental chemistry, gas chromatography - mass spectrometry, liquid chromatography, quality control - quality assurance, statistical analysis of experimental data.

Introduction Chemistry is a branch of science. There are different branches to Chemistry: Organic Chemistry Inorganic Chemistry Physical Chemistry Analytical Chemistry Organic Inorganic Chemical Analysis: is the determination of the quality and quantity of the substance. Chemistry Physical Analytical Chemistry: is concerned with the chemical characterization of matter, both qualitative and quantitative. Analytical Science

In qualitative analysis, the identity, not the amount, of metal ions present in a mixture is determined. The technique consists of selectively precipitating only a few kinds of metal ions at a time under given sets of conditions. Consecutive precipitation steps become progressively less selective until almost all the metal ions are precipitated. Other additional steps are needed to separate metal ions that precipitate together.

Since 2010, qualitative analysis practicals have been tested throughout all KCSE exams. As such, you should ensure that you know how the various organic and inorganic substances react with different solutions. Ask yourself, do you know what colour these compounds turn when burnt? When a specific solution is introduced? Do they form a soluble or insoluble product? You can get all these answers and more by using the Easy Elimu study notes on Qualitative Analysis. Don't miss out!

Note: Volumetric analysis, chemical energetics, reaction kinetics, and qualitative analysis are the most tested practicals in chemistry every year, so mastering them is paramount and will be very beneficial for you to pass your KCSE chemistry paper 3 exams.

Qualitative analysis helps detect, identify and separate anions and cations in a sample. Learn about concepts and procedures of qualitative analysis.

Qualitative and quantitative analysis are two fundamental methods of collecting and interpreting data in research. The methods can be used independently or concurrently since they all have the same objectives. They have some errors, and

Although you might not think about it immediately, how you conduct psychological research is at least as important (in fact more important) than subject of the research you conduct. Here is a quick...

Detection: –Does the sample contain substance X? Separation: –How can the species of interest be separated from the sample matrix for better quantitation and identification? Quantitation: –How much of substance X is in the sample? Identification: –What is the identity of the substance in the sample?
