Question

A solution of sodium metal in liquid ammonia acts as a strong reducing agent due to the presence of:

• A. sodium amide
• B. sodium ions
• C. sodium hydride
• D. solvated electrons

Answer 1

Answer: (D)

solvated electrons

In liquid ammonia, sodium ionizes to give $N{a}^{+}$ ion and electron. The electron is solvated with ammonia. This solvated electron (known as ammoniated electron) gives reducing properties to the solution of sodium in liquid ammonia.
