Extraction of aluminum The extraction of aluminum from its ore is a significant topic in chemistry and is often covered in the syllabus of various competitive exams, including the AIIMS entrance exam. The process of extracting aluminum involves several steps and is known as the Hall-Héroult process. Here is a brief overview of the extraction…
Oxidation Oxidation refers to a chemical process in which a substance loses electrons or increases its oxidation state. It involves the transfer of electrons from one species to another. The substance that undergoes oxidation is known as the reducing agent or reductant. Here are some key points to understand about oxidation: Oxidation has broad applications…
Methods to extract Methods of extraction are techniques used to separate and isolate desired substances from a mixture or matrix. Here are some commonly used methods of extraction: These are just a few examples of the many methods of extraction available. The choice of extraction method depends on the nature of the mixture and the…
Principles These principles provide a foundation for understanding the various aspects of chemistry and their applications in the medical field. It’s important to note that the specific emphasis and depth of coverage may vary from year to year, so it’s always best to refer to the official AIIMS website or the specific admission notification for…
General principles and processes of isolations of elements The general principles and processes of isolating elements involve various techniques and methods used to separate elements from their compounds or natural sources. Here are the key principles and processes involved: These are some of the general principles and processes involved in the isolation of elements. The…
Electrophoresis Electrophoresis is a laboratory technique used to separate charged particles, such as proteins, DNA, and RNA, based on their size, charge, or other properties. It is a fundamental method in molecular biology, biochemistry, and related fields. The principle of electrophoresis is based on the movement of charged particles in an electric field. When an…
Colloid Properties Colloid properties refer to the characteristics and behaviors of colloidal systems, which are heterogeneous mixtures consisting of two or more phases. The dispersed phase is composed of particles or droplets, while the dispersion medium is the continuous phase in which the particles are dispersed. Here are some important colloid properties: These are some…
Enzyme catalysis Enzyme catalysis refers to the process by which enzymes facilitate and accelerate biochemical reactions in living organisms. Enzymes are specialized proteins that act as biological catalysts, lowering the activation energy required for a reaction to occur. This allows the reaction to proceed at a faster rate, enabling vital cellular processes to take place.…
Catalysis of homogenous and heterogeneous Catalysis can occur in both homogeneous and heterogeneous systems, each with its own characteristics and mechanisms. Here’s an overview of catalysis in homogeneous and heterogeneous systems: Homogeneous Catalysis: In homogeneous catalysis, the catalyst and the reactants are present in the same phase, typically in a solution. The catalyst is usually…
Adsorption Adsorption is a process where molecules, ions, or particles adhere to the surface of a solid or liquid. It involves the accumulation of a substance at the interface between two phases, such as a solid-gas or liquid-gas interface. The substance being adsorbed is called the adsorbate, and the surface or material on which it…
