When an alkali metal dissolves in liquid ammonia, the solution can acquire different colours. What is the reason for this type of colour change?
Options
- AThe alkali metal undergoes a chemical reaction with ammonia, leading to the color change.
- BThe solvated electrons formed during the process absorb energy in the visible region, producing characteristic
- CThe ammonia molecules undergo a change in their electronic configuration, resulting in color variations.
- DThe color change is due to the formation of new chemical compounds between the alkali metal and ammonia.
Correct answer
B. The solvated electrons formed during the process absorb energy in the visible region, producing characteristic
Step-by-step solution
Correct Option is : (B) The solvated electrons formed during the process absorb energy in the visible region, producing characteristic colors.
