The Central Board of Secondary Education (CBSE) is a national level board of education in India for public and private schools, controlled and managed by the Government of India. Established in 1929 by a resolution of the government, the Board was an experiment towards inter-state integration and cooperation in the sphere of secondary education ...
Environmental chemistry is an interdisciplinary science that includes atmospheric, aquatic and soil chemistry, as well as heavily relying on analytical chemistry and being related to environmental and other areas of science. Environmental chemistry involves first understanding how the uncontaminated environment works, which chemicals in what ...
History of electrochemistry. Electrochemistry, a branch of chemistry, went through several changes during its evolution from early principles related to magnets in the early 16th and 17th centuries, to complex theories involving conductivity, electric charge and mathematical methods. The term electrochemistry was used to describe electrical ...
MEXICO CITY (AP) — The strange saga of how two Mexican drug lords were detained after landing in a plane in the United States in July just got stranger. The Mexican government now says it is ...
In classical electromagnetism, Ampère's circuital law (not to be confused with Ampère's force law) [ 1 ] relates the circulation of a magnetic field around a closed loop to the electric current passing through the loop. James Clerk Maxwell derived it using hydrodynamics in his 1861 published paper " On Physical Lines of Force ". [ 2 ]
Solution (chemistry) Making a saline water solution by dissolving table salt (NaCl) in water. The salt is the solute and the water the solvent. In chemistry, a solution is a special type of homogeneous mixture composed of two or more substances. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent.
Contents. Common-ion effect. In chemistry, the common-ion effect refers to the decrease in solubility of an ionic precipitate by the addition to the solution of a soluble compound with an ion in common with the precipitate. [ 1 ] This behaviour is a consequence of Le Chatelier's principle for the equilibrium reaction of the ionic association ...
