The some is and for K2MnO4, K2MnO4 - e +OH- ----- KMnO4 + KOH In general, Equivalent weight = Molar weight / … Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). 5 (a) Ferrous salts are oxidised to ferric salts. What are ten examples of solutions that you might find in your home? H2SO4 + NaOH → NaHSO4 + H2O Although one mole of H2SO4 ahs 2 replaceable H atoms … +3 In this compound, CrCl_3, it has a net charge of 0. Then we have, x-3=0 x=3 And so, chromium would have an oxidation state of +3. Potassium permanganate appears as a purplish colored crystalline solid. Capitalize the first letter in chemical symbol and use lower case for the remaining letters: Ca, Fe, Mg, Mn, S, O, H, C, N, Na, K, Cl, Al. `K_(2)MnO_(4)` में परिवर्तित किया जा सकता है `KMnO_(4)` सिवाय निम्नलिखित सभी का उपयोग करते हुए IN NEUTRAL MEDIUM:. | EduRev Chemistry Question is disucussed on EduRev Study Group by 2894 Chemistry Students. Performance & security by Cloudflare, Please complete the security check to access. Molecular weight of K M n O 4 is 1 5 8. This is how much I got. Please make sure to include clear steps on how you plugged the spectator ions back into the equation after adding the two half reactions. B.A. Balancing chemical equations. Convert grams KMnO4 to moles or moles KMnO4 to grams. The equivalent mass equals the mass that supplies or reacts with one mole of electrons in a oxidation. Equivalent weight of KMnO4 is equal with molar weight of KMnO4. Potassium Permanganate - KMnO4 is the chemical formula of Potassium permanganate, which is most commonly used as an oxidising agent in volumetric analysis. The pressure of a gas sample was measured to be 489 mmHg. In the present case-n-factor is 2 because equivalent weight is half of molecular weight. We use the most common isotopes. Can you explain this answer? Weights of atoms and isotopes are from NIST article. 43) Which is the metal as strong as steel but half as much in weight? UP CPMT 2014: What is the oxidation number of Mn in K2MnO4 ? KMnO4 is a strong oxidising agent . Thus, the equivalent mass = molecular mass/1 = molecular mass = M Hence, the equivalent mass of KMnO4 is M when it converts over to K2MnO4. K2MnO4, CAS Number: 10294-64-1 Physical Form: Green Crystals Equivalent weight= (molecular weight)/x= 157u. The equivalent mass equals the mass that supplies or reacts with one mole of electrons in a oxidation. What is the difference between saturated, unsaturated, and supersaturated?
