Unformatted text preview: ructure (the trans- isomer), the two chlorine atoms occupy
opposite corners of the octahedron. These structurally different complexes have different
physical and chemical properties. For example, the cis complex is dark purple in color,
while the trans complex looks green. In this experiment, you will prepare the chloride salt
of the trans complex. The trans complex you prepare here will be used later in
spectrophotometry and kinetics studies of its acid hydrolysis. Hereafter, we use the
symbol “en” for the ethylenediamine molecule/ligand. It is very crucial that you measure
all reagents and carry out all procedures exactly as described. Otherwise, you will
synthesize an unintended complex or obtain a mixture of products.
Please read the appropriate chapter in your textbook, as pre-laboratory preparation for
Preparation for Next Lab: You will need to retain the product for use in the
Spectrophotometry and Kinetics experiments that follow. 40 Safety:
1. Place all waste solutions/preci...
