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… In other words, change in oxidation state of KMnO4 in acidic medium is 5. The Questions and Answers of When potassium permanganate is titrated against ferrous ammonium sulphate, the equivalent weight of potassium permanganate is a) Mol. In equivalent weight. The equivalent weight of a compound is its molecular weight divided by its valence (number of electrons gained or lost by one molecule or ion of the substance in the reaction). The correct order for the decreasing acidicstrength of oxides of nitrogen is(a) N2O5 > N2O3 > N204 > NO > N2O(b) NO > N2O > N2O3 In acidic medium, the equivalent weight of KMnO₄ is . Its’ molecular weight is 39+55+64 = 158. The equivalent weight of KMnO4 is 31.6 grams in acidic medium. As Mn7+ in KMnO4 changes to Mn2+ in acidic medium; it’s equivalent weight becomes M/5 (where M is molar mass of KMnO4). For example: In potassium permanganate, permanganate ion is the active ion. The equivalent weight depends on the reaction involved. 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. x= 7-6= 1. Options (a) M/6 (b) M/5 (c) M/4 (d) M/3. Equivalent weighs of KMnO4 acidic medium, neutral medium and concentrated alkaline medium respectively ... 205 views. please give me the answer and why ? In acidic medium :M nO4− +8H + +5e− = M n2+ +4H 2 O∴ Equivalent weight = 5M M nO4− = 5158 = 31.6gmol−1In neutral or feebly alkaline medium,M nO4− +2H 2 O+3e− ⇌ M nO2 +4OH (−)∴ Equivalent weight = 3158 = 52.68gmmol−1In strongly alkaline medium :M nO4− +e− =M nO42− ∴ Equivalent weight = 1158 = 158gm/mol∴ Equivalent weight of M nO4 = in acidic, basic and neutral medium is 5: 1:3.
