What is the name of NH4OH?

Explanation:
The name for NH4OH is ammonium hydroxide. This substance is the solution formed when ammonia (NH3) dissolves in water and exists as the ammonium ion (NH4+) and hydroxide ion (OH−) in equilibrium, so the name reflects those ions in the aqueous environment. Ammonia itself is NH3, not NH4OH, so it’s not the correct name. The other options refer to different compounds—ammonium nitrate is NH4NO3, and ammonium oxide isn’t the standard name for this substance. So ammonium hydroxide is the proper designation for NH4OH.
