Therefore, the equivalent. What are ten examples of solutions that you might find in your home? The equivalent weight depends on the reaction involved. What is the difference between saturated, unsaturated, and supersaturated? There are three chlorine atoms in total, and so their total charge will be -1*3=-3. (A) +5 (B) +6 (C) +7 (D) +4. Ans: D Category: Medium Section: 5.2. eNotes.com will help you with any book or any question. Component Compounds: CID 422689 (Permanganic acid) CID 5462222 (Potassium) Dates: Modify . Other readers will always be interested in your opinion of the books you've read. Create . 27. Molecular Weight: 158.034 g/mol. IN BASIC MEDIUM:. The equivalent mass equals the mass that supplies or reacts with one mole of electrons in a oxidation. Similarities Between Photosynthesis And Cellular Respiration. IN ACIDIC MEDIUM:. The solution is titrated with M/20 Sodium EDTA and the volume is noted. The solution becomes colourless. Performance & security by Cloudflare, Please complete the security check to access. I know the equivalent weight is 31.61g. Equivalent weight of KMnO4 is equal with molar weight of KMnO4. When Ferrous sulphate acts as reductant, its equivalent weight is 1) Twice that of its molecular weight 2) Equal to its molecular weight 3) One-half of its molecular weight 4) One-third of its molecular weight 53. That is, the oxidation state changes by 1. The some is and for K2MnO4, K2MnO4 - e +OH- ----- KMnO4 + KOH In general, Equivalent weight = Molar weight / … Weight of Mohr's salt required to prepare 1000 ml of 1 M solution = 392 g. Therefore, weight of Mohr's salt required to prepare 250 ml 0.05 M Mohr's salt solution = Determination of strength of KMnO 4 using standard solution of Mohr's salt. • This is how much I got. Already a member? Whether you've loved the book or not, if you give your honest and detailed thoughts then people will find new books that are right for them. Therefore, in this disproportionation, for instance, an equivalent of K2MnO4 is (3/2) of one mole; its equivalent weight is 1.5 times its formula weight. IN ACIDIC MEDIUM:. Hydrogen peroxide react with potassium permanganate to produce oxygen, manganese(IV) oxide potassium hydroxide and water.
