Web14 Mar 2024 · Therefore, equivalent weight in neutral medium = 158/3 = 52.67g The reaction for the same is given by: M n O 4 − + 4 H 2 O + 3 e − → M n O 2 + 4 O H − Finally, let us … potassium permanganate has a molar mass of 158.034 (1) g mol−1, and reacts with five moles of electrons per mole of potassium permanganate, so its equivalent weight is 158.034 (1) g mol−1 /5 eq mol−1 = 31.6068 (3) g eq−1. Historically, the equivalent weights of the elements were often determined by studying their … See more 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 … 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, … 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of a solution of sodium hydroxide which … See more The use of equivalent weights in general chemistry has largely been superseded by the use of molar masses. Equivalent weights may be … 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 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 … See more calculation of vat formula
