Question

The electrical conductivity of sodium metal dissolved in ammonia due to

Answer 1

Answer: The electrical conductivity of sodium metal dissolved in ammonia is because of solvated electrons present in the solution.

Explanation

When the sodium metal is dropped in ammonia solution, it produces sodium ions and electrons. These sodium ions and electrons are then solvated by ammonia. Mobility of these electrons results in electrical conductivity.

Reaction follows:

$Na(s)+(x+y)NH_3(l)\rightarrow Na(NH_3)_x^+(aq)+e^-(NH_3)_y(aq)$
