# kmno4 equivalent weight in acidic medium

Although KMnO 4 acts as an oxidi sing agent in alkaline medium also , for quantitative analysis mostly acidic medium is used. Now, equivalent weight = [molar mass][/number of electrons gained/lost] Therefore,The Equivalent Weight = 158/5 = 31.6 grams. Entity corresponding to the transfer of a \$\ce{H+}\$ ion in a neutralization reaction, of an electron in a redox reaction, or to a magnitude of charge number equal to 1 in ions.. Answer: What will be the equivalent weight of KMnO4 in acidic, basic and neutral medium? Formula weight of KMnO4 is 158.04. D-artificial The correct order for the decreasing acidicstrength of oxides of nitrogen is(a) N2O5 > N2O3 > N204 > NO > N2O(b) NO > N2O > N2O3 2KMnO 4 + 5H 2 C 2 O 4 + 3H 2 SO 4 â 2MnSO 4 + 10CO 2 + K 2 SO 4 + 8H 2 O [ Check the balance ] Potassium permanganate react with oxalic acid and sulfuric acid to produce manganese(II) â¦ x= 7-6= 1. C Nitric acid is not used for the above purpose because it itself acts as a self oxidising agent and will react with the reducing agent. Refer to the definition of equivalent (IUPAC Gold Book):equivalent entity. In the acidic medium, permanganate is reduced as follows. A-number of hydrogen atoms Preparation of 0.1M standard solution of oxalic acid â Equivalent weight of oxalic acid = molecular weight / number of electrons lost by one molecule = 126/2 = 63 Solution for calculate the equivalent weight pf KMnO4 in acidic medium. \$. In the present experiment, potassium permanganate acts as a powerful oxidising agent. Equivalent weight of KMnO4 acting as an oxidant in acidic medium is? x= 7-6= 1. of electrons involved n is: MnO 4- + 8H + +5e - ---> Mn +2 + 4H 2 O So, equivalent mass = molar mass/ electrons involved = 158/ 5 â¦ The equivalent weight of KMnO4 is 31.6 grams in acidic medium. Itsâ molecular weight is 39+55+64 = 158. Since mass of KMnO4 is 158, equivalent weight in acidic medium is 31.6 grams. This site is using cookies under cookie policy. In other words, \$\pu{1 equiv}\$ is the amount of substance reacting with \$\pu{1 mol}\$ of hydrogen atom. 17.6k +. For example: In potassium permanganate, permanganate ion is the active ion. STATEMENT-1: The equivalent mass of of in acidic medium is where M=molecular mass of
