Document Summary
Transition metal complexes are highly needed compounds that take a part in the formation of anti-hiv drugs1, dyes2, cosmetics3, and most importantly, catalysts3. Since these various usages are based upon the molecular structures of a transition metal complex, it is essential to study the construction of such a complex. In this experiment, the percentage by weight of the chromium (iii) ion in the cis form of the k [cr(c 2o4)2(h 2 o)2] 2h 2 o complex is studied. [cr (c 2o 4)2( h 2o)2] 2h 2 o ion exists in two isomeric forms: the trans form, and the cis form; the latter of which will be synthesized using equation (1). K 2c r2o7+7 h 2 c2 o4(2h 2 o) 2k[cr(c 2o4)2(h 2 o)2] 2h 2 o+6co2+13 h 2 o (1)4. The resulting cis form of the k [cr(c 2o4)2(h 2 o)2] 2h 2 o complex will then be converted into cr(n o3)3 using a number of intermediate steps.
