The smallest particle of an element, which may or may not have an independent existence but always takes place in a chemical reaction is called an atom. An atom is defined as the smallest unit that retains the properties of…
Atoms are much too small to be seen; hence experiments to find out their structure and behavior have to be conducted with large numbers of them. From the results of these experiments, we may attempt to construct a hypothetical model…
A molecule is a collection of two or more atoms that are securely bound together by attractive forces or by chemical bonds. The term “atom” refers to the tiniest unit of matter that can be separated. The term “valency” refers…
Atom is the basic of all matter. They are very small and consist of even tinier particles. Neutrons, Protons, and Electrons are the basic particles making up the atom. They join together with other atoms and create matter. It takes…
Some important applications of this branch of chemistry are listed below.
Analytical chemistry is the branch which is taught in almost all schools and colleges. But the applications of it are made in pharmaceutical industries, food factories, chemical industries, agricultural industries and in scientific laboratories. The tools used for this purpose…
Two sub-branches come under analytical chemistry namely quantitative analysis and qualitative analysis which can be explained as follows. These two methods form the backbone of many educational labs of analytical chemistry. 1. Quantitative Analysis Quantitative Analysis is a method of determining…
The methods used to determine the identity and the quantity of the analytes in the field of analytical chemistry can be broadly divided into classical and instrumental methods. 1. Classical Methods 2. Instrumental Methods It can be noted that even…
Analytical chemistry involves the separation, identification, and the quantification of matter. It involves the use of classical methods along with modern methods involving the use of scientific instruments. Analytical chemistry involves the following methods: Today, the field of analytical chemistry generally involves…
Depending upon the number of alkyl or aryl groups attached to the nitrogen atom, the aliphatic or aromatic amines are classified as primary , secondary and tertiary amines.
