WebThe equivalent weight of K 2Cr 2O 7 in acid medium is equal to: A molecular weight B 1/2 molecular weight C 1/6 molecular weight D 1/5 molecular weight Medium Solution Verified by Toppr Correct option is C) In acidic medium, there is an exchange of 6 electrons hence the equivalent weight of K 2Cr 2O 7 is 61 of its molecular weight. 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of a solution of sodium hydroxide which … See more The use of equivalent weights in general chemistry has largely been superseded by the use of molar masses.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 merchandising furniture
