Current Question (ID: 18202)

Question:

$\text{The incorrect statement about the solution of electrolytes is:}$

Options:

1. $\text{Conductivity of solution depends upon the size of ions.}$
2. $\text{Conductivity depends upon the viscosity of solution.}$
3. $\text{Conductivity does not depend upon the solvation of ions present in solution.}$
4. $\text{Conductivity of solution increases with temperature.}$

Solution:

$\text{Conductivity of electrolytic solution depends on solvation of ions.}$ $\text{Explanation:}$ $\text{The solution consists of electrolytes is known as an electrolytic solution and the conductivity of electrolytic solution depends upon the following factors:}$ $\text{(i) Size of ions: As ion size increases, ion mobility decreases and conductivity decreases.}$ $\text{(ii) Viscosity of solution: Greater the viscosity of the solvent lesser will be the conductivity of the solution.}$ $\text{(iii) Solvation of ions: Greater the solvation of ions of an electrolyte lesser will be the electrical conductivity of the solution.}$ $\text{(iv) Temperature of medium: Conductivity of solution increases with increase in temperature.}$
