(a)
Answer to Problem 5E
Reaction of HgCl2 and EDTA is a complexation reaction in which Hg2+ forms complex with EDTA.
Explanation of Solution
The reaction is represented as follows:
In this reaction, Hg2+ of HgCl2 is complexed by EDTA which is a hexadentate ligand.
(b)
Interpretation:
The observation of the reaction of HgCl2 and EDTA must be explained.
Concept Introduction :
Reaction between HgCl2 and EDTA is complexation reaction involving chelating effect of EDTA, a hexadentate ligand.
(b)
Answer to Problem 5E
Ther reaction between HgCl2 and EDTA produces a clear solution.
Explanation of Solution
The reaction is represented as follows:
As seen from the reaction, one reactant (HgCl2)issolid. After the reaction it is producing a complex which is soluble in water. Thus, after the reaction, no solid residue will be left.
