Ammonium hydroxide is a bit of a misnomer. It's not actually a compound with a distinct chemical formula like, say, water (H₂O). It's a solution of ammonia (NH₃) in water (H₂O).

Here's the breakdown:

* Ammonia (NH₃): This is the primary component. It's a colorless gas with a pungent odor.

* Water (H₂O): This is the solvent. It dissolves the ammonia gas to form the ammonium hydroxide solution.

So, while we talk about "ammonium hydroxide", the elements present are nitrogen (N), hydrogen (H), and oxygen (O).
