?❤️❤️❤️ aa jao. Apparatus Setup – Potassium permanganate solution should be taken in the burette and oxalic acid solution should be taken in conical flask. 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. equivalent weight. Procedure – 1. Since mass of KMnO4 is 158, equivalent weight in acidic medium is 31.6 grams. Explanation: No explanation available. In Acidic medium, This Mn+7 goes to Mn+2 state and hence there is a net gain of 5 electrons. B-living beings The equivalent weight of KMnO4 in alkaline medium will be (a) 31.60 (b) 52.66 (c) 79.00 (d) 158.00 The equivalent weight depends on the reaction involved. Theory: Potassium permanganate is a strong oxidising agent and in the presence of sulfuric acid it acts as a powerful oxidising agent. For example: In potassium permanganate, permanganate ion is the active ion. The Mn in KMnO4 exists in +7 state. D. One-fifth of its molecular weight. Answer: What will be the equivalent weight of KMnO4 in acidic, basic and neutral medium? The equivalent weight of KMnO4 is 31.6 grams in acidic medium. x= 7-6= 1. Potassium permanganate is an inorganic compound with the chemical formula KMnO 4 and composed of K + and MnO − 4.It is a purplish-black crystalline solid, that dissolves in water to give intensely pink or purple solutions. Add your answer and earn points. Equivalent weight = Molar mass/no: of electrons lost or gained. As Mn7+ in KMnO4 changes to Mn2+ in acidic medium; it’s equivalent weight becomes M/5 (where M is molar mass of KMnO4). Half of its molecular weight. STATEMENT-1: The equivalent mass of of in acidic medium is where M=molecular mass of

The origin of carbon compounds is x= total change in oxidation number of all atoms present in a molecule= 7-2= 5. equivalent weight= (molecular weight)/x= 157/5u. click on this link eet.google.com/dqm-tfcq-fcd​, -In naming alkane the stem tells about the Join Now. 17.6k +. B. Now, equivalent weight = [molar mass][/number of electrons gained/lost] Therefore,The Equivalent Weight = 158/5 = 31.6 grams. The Questions and Answers of When potassium permanganate is titrated against ferrous ammonium sulphate, the equivalent weight of potassium permanganate is a) Mol. In acidic medium the oxidising ability of KMnO 4 is represented by the following equation. Thus, potassium permanganate reacting by double decomposition has an equivalent weight equal to its gram molecular weight, 158.038/1 g; as an oxidizing agent under different circumstances it may be reduced to the manganate ion (MnO 4 2-), to manganese dioxide (MnO 2), or to the manganous ion (Mn 2+), with… of KMnO4 = 158.04/3 = 52.68 grams/equivalent Resin is a hydrocarbon secretion of many plants, particularly coniferous trees. 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.. x= 7-6= 1. Equivalent weight of KMnO4 acting as an oxidant in acidic medium is? B-number of oxygen atoms Now, equivalent weight = [molar mass] / [number of electrons gained or lost] so, eq wt = 158/5 = 31.6 g. Now, for alkaline medium, there are two possibilities ... Login. To find the equivalent mass, divide that molar mass by the mols of electrons taken in its half reaction. Wt./6 The answer is ‘b’. Calculate the equivalent weight of kmno4 in acidic basic and neutral medium, what is cellular? The oxidising action of KMnO 4 in the acidic medium can be represented by the following equation: MnO 4 – + 8H+ +5e– → Mn2+ + 4H 2 O Potassium permanganate react with oxalic acid and sulfuric acid. Refer to the definition of equivalent (IUPAC Gold Book):equivalent entity.
