You might have gone through different types of distillation techniques. Of them azeotropic distillation is quite interesting one. This method is used to separate azeotropic solutions. As per Wikipedia, an azeotrope is a mixture which cannot be separated by simple distillation. In general, most liquid mixtures can be separated by fractional distillation (FD). During the […]

Redox titrations involve oxidative reduction reactions. This types of titrations are quite common in usage next to acid-base titrations. As the name indicates, these redox titrations are used to analyze the reducing agents or oxidizing agent. The reaction involves the transfer of electrons, hydrogen or oxygen. The principle of redox titration: The test substance if […]

Potentiometric titration is a method of chemical analysis. This technqiue relies on the measurement of electromotive force (EMF) of a solution using a set of indicator and reference electrodes. The potential or EMF of a solution depends on the nature and concentration of the ions of the test substance. The EMF or potential is measured […]

Distillation is a process of separation of a specific substance from a liquid mixture by evaporating and subsequent cooling into a separate chamber. There are different types of distillation like 1. Simple distillation 2. Fractional distillation 3. Steam distillation 4. Vacuum distillation 5. Azeotropic distillation Simple distillation Here a liquid mixture is heated in […]

Cells, in general, are designed to respond to specific signals. They can do so because of receptors on their surfaces. In general, cells respond to bio-molecules like hormones, ions, vitamins, etc. They also respond to drugs, heavy metals and poisons. But, all the body cells do not respond to all the chemical signals. To put […]
