Current Question (ID: 18248)

Question:

$\text{Salt with the highest electrolytic conductivity in solution is:}$

Options:

1. $\text{K}_2[\text{PtCl}_6]$
2. $[\text{Co(NH}_3)_3(\text{NO}_2)_3]$
3. $\text{K}_4[\text{Fe(CN)}_6]$
4. $[\text{Co(NH}_3)_4]\text{SO}_4$

Solution:

$\text{HINT: Electrolytic conduction depends on the number of ions.}$ $\text{Explanation:}$ $\text{Step 1: Electrolytic conduction in solution} \propto \text{number of ions}$ $\text{Step 2: How to find the number of ions?}$ $\text{Atom/group of atoms present outside the coordination sphere will get ionized.}$ $1.\ 2\text{K}^+ + \text{complex ion} = 3\ \text{ions}$ $2.\ 1\ \text{ion}$ $3.\ 4\text{K}^+ + \text{complex ion} = 5\ \text{ions (Highest)}$ $4.\ \text{SO}_4^{2-} + \text{complex ion} = 2\ \text{ions}$
