Document Summary
26 october 2015: comparing redox agents, reagents and properties, permanganate is a strong oxidizing agent (gains electrons easily, manganese can go from an on of +2 (likely a reducing agent) to +7 (likely an oxidizing agent) Mn2+, goes from purple to colorless. 2-, solution turns green: many redox reactions with mno4. Can be catalyzed with mn2+ or mno2: sulfite and bisulfite are common reducing agents, sodium metabisulfate: na2s2o5. Starts w/ sulfur on of +4 (max is +6) Acting as a reducing agent (getting oxidized), becomes so4. 2: oxalate as a reducing agent, c2o4. 2- when reduced forms co2: with the exception of fluorine, the halogens have many stable oxidation numbers, they all have a ground state configuration of [xx]ns2np5. Therefore, they can have on ranging from -1 to +7. (triiodide ion) which is in an equilibrium (i3: i2 is prepared from i3, halogens will be separated from the ions in solution by extraction.
