    In this experiment‚ 5.281g of trans isomers of [Co(en)2Cl2]Cl was synthesized from 12.249g of CoCl2▪6H2O. First‚ CoCl2▪6H2O was reacted with ethlenediamine (NH2CH2CH2NH2) that formed [Co(en)2(H2O)2]Cl. Then the [Co(en)2(H2O)2]Cl was reacted with H2O2 to change the cobalt’s charge to cobalt(III) from cobalt(II). Finally HCl was added into the solution to form [Co(en)2Cl2]Cl. The percent yield was 45.51%.To synthesis trans isomers of [Co(en)2Cl2]Cl‚ distilled water was first mixed with CoCl2▪6H2O‚
