Document Summary

Tips: focus on coordination compounds, focus on redox reactions, redo or look through lab reports, metal salt + water =hexaaqua complex. Identifying oxidizing vs reducing agent and their half reactions. , bro4: purple disappears, oxidation of permanganate in a basic medium: (mno4)- mno2, formation of brown/black ppt, oxidation of permanganate in a very basic medium: (mno4)- (mno4)2, solution turns green. Experiment 5, redox reactions and spectroscopy: substances used and their color: Relative strengths of oxidizing agents and reducing agents: Experiment 6, comparing strengths of oxidizing/reducing agents: when oxalate (c2o4, when metabisulfite, s2o5. 2-) acts as a reducing agent it becomes co2. 2-, (which dissolves in water to form bisulfite, hso3. ) acts as a reducing agent, it becomes so4. Preparations of halogens: cl2 from hcl and bleach solution (containing 4% naclo, cl- + clo- cl2, oxidation: cl- cl2, reduction: clo- cl2, br2 from nabr and nabro3, br- + bro3. I3: the halogens will be separated from the ions by extraction.
