Oxidation number of KMnO4? Flying Dragon. First, we need to see what are the oxidation numbers of all of the other elements. The oxidation number of Mn in KMnO4 is - 5475538 Direction: Activities commonly done at home, school, and community are provided inthe table below. let Oxidation number of Mn be x oxidation number of O is -2. therefore Oxidation number of KMnO4= +1+(x)+(4)(-2)=0 1+x+(-8)=0 1+x-8=0 1+x=8 x=8-1 x=7. H2O2 + KMnO4 + H2SO4 = O2+ H2O + MnSO4 + K2SO4. ᴡʜᴀᴛ ᴅᴏ ʏᴏᴜ ᴍᴇᴀɴ ʙʏ sᴏʟ ᴀɴᴅ sᴏʟᴜᴛɪᴏɴ?? It became popular in the 1960s.
