Sodium in liquid ammonia is strongly reducing due to the presence of the presence of solvated electrons.
Reduction is lowering oxidation number because element gain electrons.
General chemical reaction of sodium in liquid ammonia:
Na + (x+y)NH3 → [Na(NH3)x]+ + [e(NH3)y]−
Solution of sodium in liquid ammonia has unpaired solvated electrons.
They are very strong reducing agents that in this example reduced sodium (Na).
Solvated electrons are free electron ina solution. They are the smallest anions.
Solvated electrons are very stable in solution of ammonia.
Liquid ammonia dissolves all of the alkali metals (sodium is one of them).
