A) \[solvated\text{ }N{{a}^{+}}\,\,ions\]
B) solvated electrons
C) \[solvated\text{ }N{{a}^{-}}_{2}\,\,ions\]
D) solvated protons
Correct Answer: B
Solution :
When sodium metal is dissolved in liquid ammonia to form coloured solution. Dilute solutions are bright blue in colour due to the presence of solvated electrons. \[Na+(x+y)N{{H}_{3}}\,\,\to \,\,{{\left[ Na{{(N{{H}_{3}})}_{x}} \right]}^{+}}\,+\,{{\underset{Blue\,\,colour}{\mathop{\left[ e{{(N{{H}_{3}})}_{y}} \right]}}\,}^{-}}\]
