The conductivity of a solution increases with the increase of concentration of ions in it.

Explanation:

The conductivity of a solution increases with the increase of concentration of ions in it.

In the case of a #0.001M# sodium chloride #NaCl# solution, the concentrations of ions are:

#[Na^+]=0.001M#
#[Cl^-]=0.001M#

However, for the #0.001M# solution of ferric chloride #FeCl_3#, the concentrations of ions are:

#[Fe^(3+)]=0.001M#
#[Cl^-]=0.003M#

Therefore, there are more ions in the solution of ferric chloride than that of sodium chloride, and thus the conductivity of the ferric chloride solution will be higher.
