Experiment D: Separation of Alcohols by Fractional Distillation Pre-lab Properties: Propanol‚ butanol‚ methanol Purpose: To separate two alcohols by distillation and analyze results with GC. Do not plug mantle directly into electrical outlet‚ use controller! Use 40/60 mol percent propanol/butanol (no cyclohexane or toluene are used in this lab because they are more toxic) Set up fractional distillation Set heat at highest level to start‚ then turn back down to 60-80% when vapor starts up column

Coordination Complexes of Cobalt Advanced Inorganic Chemistry Lab 02/27/2015 Abstract When the transition metal‚ cobalt‚ forms a complex involving a nitrate ion‚ the ligand has the ability to coordinate via N or O. The ability of the nitrate to attach via the N or O gives rise to the term‚ linkage isomers and can affect the functionality of the complex with other molecules. To explore structural differences between complexes‚ pentaaminechlorocobalt (III) chloride‚ pentaaminenitritocobalt (III)
