Statement 1: As the very dilute solutions of alkali metals in liquid ammonia are made more concentrated, the molar conductivity at first decreases, reaching a minimum at about 0.05 molar; therefore, it increases again.Statement 2: The molar conductivity of the saturated solution of the alkali metals in liquid ammonia at -330C is comparable to that of a metal.

These dilute solutions conduct electricity and the conductivity is similar to that of the pure metals. Conduction is due mainly to the presence of solvated electrons. As the solutions are made more concentrated, the molar conductivity at first decreases, reaching a minimum at about 0.05 molar; therefore, it increases again until in saturated solutions it is comparable to that of the metal.
