Mno2 to mno4- half reaction
WebMnO 4- --> MnO 2 Next, balance O's using H 2 O as if in acid solution by adding H 2 O's as necessary to the side deficient in O. In this case, 2 H 2 O's are needed on the right hand side of the half reaction: MnO 4- --> MnO 2 + 2 H 2 O To balance H's, add as many H + ions as needed to the side deficient in H, as if in acid solution. WebAnswer: In acid medium KMnO4 undergoes redox reactions with suitable reducing agents like Oxalic acid solution , Ferrous sulphate soon, SO2 gas etc In any redox reactions two …
