This trick takes you through the steps to balance redox reactions that occur under Acidic conditions. No of gram equivalent = no. For the best answers, search on this site https://shorturl.im/axu6J. The molecular formula would be : 5 H2O2 + 2 KMnO4 + 3 H2SO4 --> 2 MnSO4 + K2SO4 + 5 O2+ 8 H2O The net ionic equation would be: 5 H2O2 + 2 MnO4^- + 6 H^+ --> 2 Mn+2 + 5 O2+ 8 H2O Redox Reactions. What is the percentage purity of H2O2? What is the chemical equation for the reaction between Potassium Permanganate(KMnO4) and Hydrogen Peroxide(H2O2)? 1 decade ago . Favorite Answer. Thermal decomposition: When solid potassium permanganate is heated it undergoes decomposition. Calculate the energy in joule corresponding to light of wavelength 45 nm (Planck's constant, $h=6.63\times10^{-34}$ Js; speed of light, $c=3\times 10^{8}$. Hydrogen peroxide react with potassium permanganate and sulfuric acid H2O2 + H2SO4 + KMnO4 = O2 + H2 + MnSO4 + K2SO4 or, After balancing the Redox reaction 5 H 2 O 2 + 3 H 2 SO 4 + 2 KMnO 4 = 5 O 2 + 8 H 2 O + 2 MnSO 4 + K 2 SO 4 The sample of Sulphuric acid is 49% by mass, 100 ml of Iit titration with 12 N(Normal) NaOH required 50ml of NaOH solution. $\ce{H2SO4}$ is stable to oxidization. The number of moles of KMnO4 required to react with 5 moles of H2O2 in acidic medium is ? KMnO4 and H2O2 react mainly in the medium of H2SO4. Hence for 1 mole of , we need 2= 2.5 moles of molecules.
