(a) Interpretation: Equations which represent the given observation that when a mixture of M g ( O H ) 2 ( s ) and Z n ( O H ) 2 ( s ) is treated with N H 3 ( a q ) , the Z n ( O H ) 2 dissolves but the M g ( O H ) 2 ( s ) is left behind should be determined. Concept introduction: A complex ion is formed when a metal ion reacts with a Lewis base in solution. This reaction is characterized in terms of chemical equilibrium . A complexion comprises of a ligand and a metal ion as a result of an interaction of Lewis acid-base. Metal ion which is positively charged functions as a Lewis acid. Lewis base or the ligand has one or more lone pairs of electrons. For example, Cu 2 +, which is a highly charged and small metal ion having the major tendency to function as Lewis acids, consequently exhibiting the greatest affinity to form complex ions.
