Question
What is the formula for liquid ammonia? Account for the basic nature of this compound.
✓

Answer

The formula of liquid ammonia is $NH_{3.}$​​​​​​​
Liquid ammonia is liquefied ammonia and is basic in nature. It dissolves in water to give ammonium hydroxide which ionizes to give hydroxyl ions.
$NH_3 + H_2O \rightarrow NH_4OH$
$NH_4OH ⇌ NH_4^++ OH^-​​​​​​​$​​​​​​​
Therefore it turns red litmus blue and phenolphthalein solution pink.
