Question

The complex that will exhibit maximum ionic conductivity in aqueous solution is:

A

K4[Fe(CN)6]K_4[Fe(CN)_6]

B

[Co(NH3)6]Cl3[Co(NH_3)_6]Cl_3

C

[Cu(NH3)4]Cl2[Cu(NH_3)_4]Cl_2

D

[Ni(CO)4][Ni(CO)_4]

Step-by-Step Solution

The ionic conductivity of a coordination compound in an aqueous solution is directly proportional to the total number of ions it furnishes upon dissociation . Let us examine the dissociation of the given complexes:

  1. K4[Fe(CN)6]→4K++[Fe(CN)6]4−K_4[Fe(CN)_6] \rightarrow 4K^+ + [Fe(CN)_6]^{4-} (Total 5 ions)
  2. [Co(NH3)6]Cl3→[Co(NH3)6]3++3Cl−[Co(NH_3)_6]Cl_3 \rightarrow [Co(NH_3)_6]^{3+} + 3Cl^- (Total 4 ions)
  3. [Cu(NH3)4]Cl2→[Cu(NH3)4]2++2Cl−[Cu(NH_3)_4]Cl_2 \rightarrow [Cu(NH_3)_4]^{2+} + 2Cl^- (Total 3 ions)
  4. [Ni(CO)4][Ni(CO)_4] is a neutral molecular complex and does not ionize in water (0 ions). Since K4[Fe(CN)6]K_4[Fe(CN)_6] produces the maximum number of ions in an aqueous solution, it will exhibit the highest ionic conductivity.
