What is the colour and magnetic behaviour of Na in liquid NH3 solution in hot and cold conditions
Answers
Answer:
this is what happens when it dissolved
Explanation:
By the reaction of sodium with liquid ammonia sodium amide can be prepared. Sodium(alkali metal) dissolves dissolves in liquid ammonia solution to form a blue solution characteristic of a solvated electron in liquid ammonia, which is conducting in nature, due to ammoniated electrons (solvated electron).
A paramagnetic and blue coloured solution is formed when Na is dissolved in liquid NH3.
- Sodium metal dissolves in liquid ammonia and gives deep blue solution which are conducting in nature.
- The reason of blue colour of the solution is the presence of ammoniated electrons that absorbs radiation imparting blue colour to it.
- The solution is paramagnetic and on standing slowly liberates hydrogen gas which results in the formation of amide.
- In conc. solution, this blue colour changes to bronze and becomes diamagnetic.
