Textbooks published by NCERT are prescribed by the Central Board of Secondary Education (CBSE) [8] from classes I to XII, with exceptions for a few subjects, especially for the Class 10 and 12 Board Examination. Around 19 school boards from 14 states have adopted or adapted the books. [11]
Electrochemistry. English chemist John Daniell (left) and physicist Michael Faraday (right), both credited as founders of electrochemistry. Electrochemistry is the branch of physical chemistry concerned with the relationship between electrical potential difference and identifiable chemical change. These reactions involve electrons moving via an ...
IISER Aptitude Test (IAT) is an Indian computer-based test for admission to the various undergraduate programs offered by the seven IISERs, along with IISc Bangalore and IIT Madras. [3][4][5][6] It is the only examination to get admission into the. 5-year BS-MS Dual Degree Programs of the IISERs, 4-year BS Degree Programs of IISER Bhopal, and.
Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
The hydrogen electrode is based on the redox half cell corresponding to the reduction of two hydrated protons, 2H+(aq), into one gaseous hydrogen molecule, H2 (g). General equation for a reduction reaction: The reaction quotient (Qr) of the half-reaction is the ratio between the chemical activities (a) of the reduced form (the reductant, ared ...
The Debye–Hückel theory was proposed by Peter Debye and Erich Hückel as a theoretical explanation for departures from ideality in solutions of electrolytes and plasmas. [1] It is a linearized Poisson–Boltzmann model, which assumes an extremely simplified model of electrolyte solution but nevertheless gave accurate predictions of mean activity coefficients for ions in dilute solution.
Oscillogram made in July 1972 by Briggs and Rauscher. The Briggs–Rauscher oscillating reaction is one of a small number of known oscillating chemical reactions.It is especially well suited for demonstration purposes because of its visually striking colour changes: the freshly prepared colourless solution slowly turns an amber colour, then suddenly changes to a very dark blue.
Electrosynthesis. In electrochemistry, electrosynthesis is the synthesis of chemical compounds in an electrochemical cell. [1][2][3][4] Compared to ordinary redox reactions, electrosynthesis sometimes offers improved selectivity and yields. Electrosynthesis is actively studied as a science and also has industrial applications.
