Potassium hexacyanoferrate$(II)$

Vedclass · Answer

(D) The molar conductivity of an electrolyte solution is directly proportional to the number of ions produced per formula unit in the solution. $(a)$ $[Fe(CO)_5]$ is a neutral complex,it does not dissociate into ions. $(b)$ $[Cr(H_2O)_5Br]Br_2$ dissociates as $[Cr(H_2O)_5Br]^{2+} + 2Br^-$,providing $3$ ions. $(c)$ $[Co(NH_3)_4Cl_2]Cl$ dissociates as $[Co(NH_3)_4Cl_2]^+ + Cl^-$,providing $2$ ions. $(d)$ $K_4[Fe(CN)_6]$ dissociates as $4K^+ + [Fe(CN)_6]^{4-}$,providing $5$ ions. Since $K_4[Fe(CN)_6]$ produces the maximum number of ions $(5)$,it exhibits the highest molar conductivity. Thus,$(d)$ is the correct answer.

Which one of the following has the highest molar conductivity?
