Ammonium hydroxide is an aqueous solution of ammonia (NH₃) in water. When ammonia gas dissolves in water, some of it reacts with H₂O molecules to form ammonium (NH₄⁺) and hydroxide (OH⁻) ions: 𝑁 𝐻 3 + 𝐻 2 ⇌ 𝑁 𝐻 4 + + 𝑂 𝐻 − NH 3 ​ +H 2 ​ O ⇌NH 4 + ​ +OH − 📌 In practice, the term ammonium hydroxide (NH₄OH) is used to refer to this solution, although the pure substance (isolated NH₄OH) does not exist in a stable form—it is just a way of chemically representing ammonia dissolved in water. Characteristics: Colorless liquid with a strong, penetrating odor (typical ammonia smell). Weak base (less alkaline than caustic soda, for example). Very soluble in water. Main uses: Chemical industry: precursor to ammonium salts (such as ammonium nitrate, ammonium sulfate). Cleaning products: present in household cleaners, degreasers, and stain removers. Water treatment: helps adjust pH and remove heavy metals. Textile and leather industry: used to treat fibers and hides. Pharmaceutical and cosmetics: in controlled concentrations, it can be used in cleaning solutions or as a pH regulator. 👉 In short: ammonium hydroxide is simply ammonia dissolved in water, forming a basic solution with a strong odor and multiple industrial applications.
