Question

Maximum conductivity is seen in:

• A. $K_3\left[Fe\right(CN{)}_6]$ (0.1 M solution)
• B. $K_2\left[Ni\right(CN{)}_4]$ (0.1 M solution)
  
• C. $FeS{O}_4.A{l}_2(S{O}_4{)}_3.24H_{2}O$ (0.1 M Solution)
  
• D. $N{a}_3\left[Ag\right(S_2{O}_3{)}_2]$ (0.1 M solution)

Answer 1

The correct option is C $FeS{O}_4.A{l}_2(S{O}_4{)}_3.24H_{2}O$ (0.1 M Solution)


$FeS{O}_4.A{l}_2(S{O}_4{)}_3.24H_{2}O$ is a double salt which on ionization gives $F{e}^{2+},2A{l}^{3+},4S{O}_4^{2-}$ ions. Hence, it's conductivity would be maximum.
