Covalent bond, Coordinate covalent bond, and Types and Properties
Coordinate covalent bond, covalent bond, their properties, examples as well as polar and nonpolar bonds have been discussed in this post. Covalent bond is a type of chemical bond which is formed by the mutual sharing of two electrons between combining atoms. Covalent bond definition A bond formed by the mutual sharing of electrons between […]
Ionic bond, properties, covalent bond vs ionic bond
Ionic bond is a type of chemical bond which is formed between two or more than two atoms by the transfer of one or more electrons among atoms. Ionic bond definition Ionic bond can be defined as a bond that is formed between two or more than two atoms by the transfer of electrons among […]
Chemical Bonding Class 11 notes, Electronic theory of Chemical bond, Types of Bond
Chemical bonding is a force of attraction that binds the atoms of the elements together. In other words, the force which binds atoms of elements together in a compound is called a chemical bond. Cause of chemical bonding(Formation of chemical bonding) The atoms of the elements other than noble gases tend to remain in a […]
Size-Exclusion Chromatography: Definition, Theory, and Application
Size-exclusion chromatography is a type of chromatography in which separation is based on the molecular size and shape of species present in the sample. It is also known as “gel permeation chromatography”. The term “gel permeation” is commonly used in polymer science for non-aqueous separations. SEC is defined as the differential elution of solutes, from […]
Affinity Chromatography, Principle, Instrumentation, and Application
Affinity chromatography is a type of chromatographic technique in which separation is based on the various types of specific affinities between a target molecule and a specific ligand coupled to a chromatography medium. Affinity Chromatography Principle Affinity chromatography is a method of separating the biochemical mixture on the basis of the special affinity of one […]
Protein purification by ion-exchange chromatography: (1)Principle and (2) procedure of separation of protein
Protein purification by ion-exchange chromatography Ion-exchange chromatography is a type of chromatography that is widely used in the purification of the protein, amino acids, etc. Ion exchange chromatography separates biomolecules according to the types and strength of their charge. There are two types of ion exchange viz. cation exchange and anion etc. (1) Principle of […]
Ion Exchange Chromatography,Defination, principle and advantages disadvantages.
Ion exchange chromatography is a technique that allows the separation of ions and polar molecules based on their affinity to the ion exchanger. It can be used for different charged molecules including large proteins, small nucleotides, and amino acids. This method of separation is based on the use of ion-exchange resins as packing materials in […]
Chromatography, Types , Principle of chromatography and its applications
Chromatography is an analytical technique to separate the components of a mixture which are distributed between a stationary phase and a flowing mobile phase according to the rate at which these components are transported through the stationary phase. Chromatography is an analytical technique that is used for the separation, purification, isolation, and identification of chemicals […]
Fractional distillation of Crude oil, Process of fractional distillation of Crude oil
The separation of crude oil/petroleum products into different chemical compounds can be done by using fractional distillation. Crude oil is a mixture of hydrocarbon of different lengths and sizes. Different hydrocarbon has different chain lengths and hence they have different boiling points. Generally, smaller molecules have less carbon in them and therefore, have lower boiling […]
Fractional distillation: Simple distillation vs Fractional distillation(8 easy differences)
Fractional distillation is the process of separation of chemical mixtures employing heat to separate the components present in the mixture. It is one of the popular separation methods in chemistry experiments. Principle of fractional distillation The basic principle of fractional distillation is that different liquids boil at different temperatures. When the mixture is heated, the […]
Simple Distillation Definition, Disadvantages, Apparatus Setup
In simple distillation, the liquids mixture is simply heated to boiling points and condensing back them to liquids.Condition: This methods is only effective if the liquid of mixture has sufficiently different boiling temperature i.e at least 25 degree Celcius difference in boiling points. If the liquid contains nonvolatile impurities, then it can be a best […]
Distillation Definition and Types of Distillation
Distillation Definition: Distillation is a method of purification in which a liquid is converted into vapor form and which is condensed back to liquid form. It is used in the separation of liquids from nonvolatile solids impurities. Moreover, it has wide application in the separation of the mixture of two or more liquids having different […]
