How does ion size affect conductivity? + Example

Webshow comparatively low conductivities in their solutions. Ionic size & mobility: * The ionic mobility decreases with increase in its size and hence conductivity also decreases. E.g. In molten state, the conductivities of lithium salts are greater than those of cesium salts since the size of Li+ ion is smaller than that of simply hired top 20 jobs
