The electrical conductivity of KI(aq) is greater than the electrical conductivity of H_2O(l) because the KI(aq) contains mobile what?

Because the $K I \left(a q\right)$ solution contains aquated ions............
$K I \left(s\right) \stackrel{{H}_{2} O}{\rightarrow} {K}^{+} \left(a q\right) + {I}^{-} \left(a q\right)$
The $\left(a q\right)$ designates that the metal (or non-metal) ion is solvated by, aquated by several water molecules, i.e. ${\left[K {\left(O {H}_{2}\right)}_{6}\right]}^{+}$ or something similar..... And these species can carry an electrical current.......
