Interpretation:
The given observation that
Concept introduction:
A complex ion is formed when a metal ion reacts with a Lewis base in solution. This reaction is defined in terms of
The 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, Cu2+, which is a highly charged and small metal ion having a significant tendency to function as Lewis acids, consequently exhibiting the greatest affinity to form complex ions.
The development of a complexion is a stepwise procedure, and every step has its equilibrium constant. When two of the equations are added together, the equilibrium constants multiply.
(b)
Interpretation:
In the given observation the reason by which Agl will dissolve in an aqueous solution of sodium thiosulfate should be determined in terms of complex-ion formation.
Concept introduction:
A complex ion is formed when a metal ion reacts with a Lewis base in solution. This reaction is defined 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.
