Oxidation Oxidation is a chemical process that involves the loss of electrons or an increase in the oxidation state of an atom, ion, or molecule. It is often associated with the addition of oxygen, the removal of hydrogen, or the removal of electrons from a species. Oxidation reactions are typically accompanied by reduction reactions, forming…
Methods to extract Methods to extract refer to the techniques used to separate or isolate specific components from a mixture or source material. There are various methods of extraction employed in different fields, including chemistry, biology, and industry. Here are some common methods of extraction: These are just a few examples of extraction methods commonly…
Principles If you’re specifically looking for the principles covered in the AIIMS chemistry syllabus, here are some fundamental principles that are commonly included: It’s important to note that the AIIMS chemistry syllabus may vary over time, and it’s always advisable to refer to the official syllabus provided by AIIMS or consult the relevant department for…
General principles and processes of isolations of elements The general principles and processes of isolation of elements involve various techniques and methods used to extract and obtain pure elements from their ores or sources. Here are the fundamental principles and processes commonly employed: These general principles and processes of isolating elements form the basis for…
Types of Emulsions There are various types of emulsions based on their composition and structure. The main types of emulsions are: These are some of the common types of emulsions. Each type has unique properties and applications, and their formation and stability depend on factors such as the nature of the dispersed and continuous phases,…
Electrophoresis Electrophoresis is a laboratory technique used to separate and analyze molecules based on their size and charge. It involves applying an electric field to a gel or liquid medium containing the molecules of interest. The molecules, such as proteins or nucleic acids, move through the medium under the influence of the electric field. In…
Brownian movement Brownian movement, also known as Brownian motion, is the random motion of microscopic particles suspended in a fluid (liquid or gas). It was first observed by the botanist Robert Brown in 1827 and later explained by Albert Einstein in 1905. Brownian movement occurs due to the continuous collision of the fluid molecules with…
Colloid Properties Colloid properties refer to the characteristics and behaviors exhibited by colloidal systems. Colloids are heterogeneous mixtures in which particles (dispersed phase) are evenly distributed within a continuous medium (dispersion medium). Here are some key properties of colloids: Understanding the properties of colloids is essential in various scientific and technological applications, including medicine, materials…
Enzyme Catalysis Enzyme catalysis refers to the process by which enzymes accelerate and facilitate chemical reactions in living organisms. Enzymes are specialized proteins that act as biological catalysts, increasing the rate of specific biochemical reactions without being consumed in the process. Key concepts related to enzyme catalysis include: Understanding enzyme catalysis is crucial in many…
Catalysis of homogenous and heterogeneous Catalysis can be classified into two main types: homogeneous catalysis and heterogeneous catalysis. Both homogeneous and heterogeneous catalysis are important in various industrial and laboratory processes. They play a crucial role in enhancing reaction rates, improving selectivity, and enabling the efficient use of resources in chemical transformations. The AIIMS-SYLLABUS for…
