Explanation:
Alkali metals such as Na, K, etc. dissolve in liquid ammonia to form a deep blue solution that conducts electricity. This is due to the formation of ammoniated electrons, which are solvated electrons in liquid ammonia. The solvated electrons are responsible for the electrical conductivity of the solution.
Formation of ammoniated electrons:
When an alkali metal is added to liquid ammonia, it reacts with the solvent to form ammoniated cations and solvated electrons. For example, when sodium is added to liquid ammonia, it reacts as follows:
Na + NH3 → Na+ (NH3)x + e- (NH3)x
The reaction produces sodium cations and solvated electrons, which are surrounded by ammonia molecules. The solvated electrons are responsible for the electrical conductivity of the solution.
Conductivity of the solution:
The solution of alkali metals in liquid ammonia conducts electricity like a metallic conductor. The solvated electrons are free to move throughout the solution, carrying the charge. The conductivity of the solution depends on the concentration of solvated electrons, which is affected by the concentration of the alkali metal and the temperature of the solution.
Conclusion:
In conclusion, the solution of alkali metals in liquid ammonia conducts electricity due to the formation of solvated electrons. The solvated electrons are responsible for the electrical conductivity of the solution, and their concentration depends on the concentration of the alkali metal and the temperature of the solution.
