It was rediscovered by British chemist Henry Condy who manufactured disinfectants known as 'Condy's crystals', potassium permanganate became a big success. structure is present in tetrahedral geometry. Care must be taken as overuse of this chemical may cause irritation and burns. Reactions of Potassium Permanganate (KMnO, Most of the reactions with Potassium permanganate are redox reactions, (a chemical reaction in which one substance is oxidized and another is reduced). By gradual addition of KMnO4 into concentrated H2SO4, Mn2O7 as a strong oxidant is produced with oily green color. Secondly, permanganate refers to a polyatomic ion, not a compound, and thirdly, compounds, like solid KMnO4, are very, very dark purple, almost black. Please register to post comments. First of all, the question is about "manganate", not "permanganate". Ltd. Download Solved Question Papers Free for Offline Practice and view Solutions Online. Why does the colour of potassium permanganate changes to brown when react with ethanol? The reaction between KMnO4 and Mohr’s salt is a redox reaction and the titration is therefore called a redox titration. Mohr’s salt is the reducing agent and KMnO4 is the oxidizing agent. [Pt (Cl) (py) (NH3) (NH2OH)]+Â  is square planar complex.The structures are formed by fixing a group and then arranging all the groups. As with acid-base titrations, a redox titration (also called an oxidation-reduction titration) can accurately determine the concentration of an unknown analyte by measuring it against a standardized titrant. 18.
