COORDINATION COMPOUNDS: * FLEXIDENTATE CHARACTER OF POLYDENTATE LIGANDS; * Poly dentate ligands have flexi dentate character in the sense that all donors atoms may not form coordinate bonds with the central metal atom or ion. For example; EDTA which is the hexa dentate ligand also acts as tetra dentate or penta dentate in certain complexes. Similarly sulphate ion‚ which is a bi dentate ligand‚ also acts as a mono dentate ligand in certain complexes‚ e.g. in [Co(SO4)(NH3)5]Cl. * LABILE

Theory: Distillation is the conversion of a mixture of substance into vapors which is afterwards condensed to the liquid form. It cans separation or purification of substances by taking advantage of differences in volatility. The purpose of this lab is comparing the efficiency of two distillation methods with the mixture of ethanol and 1-butanol. in theory the fractional distillation should be more efficient because of the steel sponge. The sponge acted as surface area for gas to condense on. This
