Figure 1 shows how the relative electrical conductivity of a lithium-ion electrolyte solution changes as the salt concentration increases.

A line graph plotting relative conductivity against salt concentration. The x-axis is 'Concentration (mol dm^{-3})' ranging from 0.0 to 2.0. The y-axis is 'Relative Conductivity' ranging from 0.0 to 10.0. The curve starts at (0.0, 0.0), climbs smoothly to a maximum at (1.0, 9.0), and then decreases steadily down to (2.0, 2.5).

Describe how the relative conductivity of this electrolyte solution changes as its concentration increases from 0.0 to 2.0 mol dm−3^{-3}−3.
