Equivalent Weight - University of California, Los Angeles
WebThe equivalent of any substance is given by the charge it carries on itself. Thus, the equivalent weight is obtained by the ratio of the molar mass of the substance and the number of equivalents. It can be mathematically represented as. Equivalent weight = Molar Mass number of equivalents . WebT he Department of Chemistry offers four options for bachelor of science degree, all designed to give students a broad background in the basic divisions of chemistry: analytical, biochemistry, inorganic, organic, and physical.. Option 1 provides considerable concentration in chemistry while permitting a wider selection of electives. It should meet … In chemistry, equivalent weight (also known as gram equivalent ) is the mass of one equivalent, that is the mass of a given substance which will combine with or displace a fixed quantity of another substance. The equivalent weight of an element is the mass which combines with or displaces 1.008 gram of hydrogen or … See more The first equivalent weights were published for acids and bases by Carl Friedrich Wenzel in 1777. A larger set of tables was prepared, possibly independently, by Jeremias Benjamin Richter, … See more When choosing primary standards in analytical chemistry, compounds with higher equivalent weights are generally more desirable because weighing errors are reduced. An example is the volumetric standardisation of a solution of sodium hydroxide which … See more In polymer chemistry, the equivalent weight of a reactive polymer is the mass of polymer which has one equivalent of reactivity (often, the mass of polymer which corresponds to one mole of reactive side-chain groups). It is widely used to indicate the … See more The use of equivalent weights in general chemistry has largely been superseded by the use of molar masses. Equivalent weights may be calculated from molar masses if the … See more The term “equivalent weight” had a distinct sense in gravimetric analysis: it was the mass of precipitate which corresponds to one gram of analyte (the species of interest). The different definitions came from the practice of quoting gravimetric results as See more chef peter chang
