A solution of sodium metal in liquid ammonia acts as a strong reducing agent due to the presence of:
Unreacted sodium metal can be removed from liquid ammonia safely by:
Unreacted sodium metal can be removed from liquid ammonia safely by adding ammonium chloride. The reaction is as follows:
$$2Na\, +\, 2NH_4Cl \, \rightarrow\, 2NaCl\, + \, 2NH_3 \, +\, H_2$$
A solution of sodium metal in liquid ammonia acts as a strong reducing agent due to the presence of:
Highly pure dilute solution of sodium in liquid ammonia :
When an alkali metal dissolves in liquid ammonia the solution can acquire different colours. Explain the reasons for this type of colour change.
The alkali metals dissolve in ammonia to give a deep blue solution which is conducting in nature. $$M +(x + y) NH_3 \rightarrow [M(NH_3)_x]^{2+} + 2[e(NH_3)y]^-$$ Which of the following is not true about the solutions are alkali metals in liquid ammonia?
Select the correct statement(s):
The alkali metals dissolve in liquid $$NH_3$$, it is found that :
A solution of sodium in liquid ammonia is blue in colour due to:
Which of the following statement about solution of alkali metals in liquid ammonia is correct ?
Ammoniated solutions of alkali metals are reducing agents due to the presence of free ammoniated or solvated electrons that can reduce: (I) $$O_{2} $$ to $$O_{2}^{2-} $$ (II) $$K_{2} [Ni(AN)_4] $$ to $$K_{4} [Ni(CN)_4] $$ (III) Aromatic ring (IV) Non-terminal alkyne Choose the correct code:
Which of the following metal(s) in liquid $$NH_{3} $$ with low conc. is not paramagnetic ?
