Explain the following experimental observations:
a) Two coordination compounds with the same empirical formula, Co(NH3)5(NO3)2SO4, are
each added to water to make 0.1 M solutions. One solution remains neutral but the other
becomes basic. Give the formula for each compound and name the type of isomerism
represented by these two compounds.
b) The complex ion [PtCl2(NH3)2]2+ is square planar and has two different isomers. One of the
compounds is polar and the other is nonpolar. Draw the compounds and determine which
compound is polar.
Solution
b)[PtCl2(NH3)2]2+
When both the Cl's are opposite to each other or both NH3's are opositopto each other-non
polar
Other wise when Cl is opposite to NH3 it is polar
