Question

Sodium dissolves in liquid ammonia to form a solution which shows electrical conductivity

Answer 1

Answer:

na +nh3=nanh2+h2

Explanation:

it conduct electricity because of presence of ammoniated electron (solvated electron)

Answer 2

Sodium dissolves in liquid ammonia to form a solution which shows electrical conductivity due to the presence of electrons and metal ions.

Explanation:

• It is known that sodium is an alkali metal and when it is added to liquid ammonia then it readily dissolves in it. This dissolution leads to the formation of a blue color solution.

• This blue colored solution actually contains ammoniated electrons. As, electricity is the flow of electrons or ions so, this solution is able to conduct electricity.

• The reaction equation of this solution is as follows.

           $2Na + 2NH_{3} \rightarrow 2NaNH_{2} + H_{2}$

Since, the blue color of solution is due to solvated electrons. Hence, the solution is able to conduct electricity or conductive in nature.
