What are the chemical properties of ammonia water?

Ammonia water has alkaline properties: it can turn colorless phenolphthalein test solution red, purple litmus test solution blue, and wet red litmus paper blue.
This method is commonly used in the laboratory to detect the presence of NH3. Can react with acids to generate ammonium salts. When concentrated ammonia water meets volatile acids such as concentrated hydrochloric acid and concentrated nitric acid, it produces white smoke.
Instability: Ammonia monohydrate is unstable and easily decomposes into ammonia and water when heated.
Flammability: It can react with oxygen to produce water and nitrogen, making it a promising harmless fuel. But the disadvantage is that it must burn in pure oxygen.
Sedimentation: Ammonia water is a good precipitant, which can react with various metal ions to generate insoluble weak bases or amphoteric hydroxides.
Reductive: Ammonia water exhibits weak reducibility and can be oxidized by strong oxidants.
Oxidation: Hydrogen in the+1 oxidation state of ammonia molecules exhibits weak oxidation and can oxidize strong reducing agents.
