WebJan 4, 2024 · First, you cannot get ammonia hydroxide solution of p H 12.8 at the room temperature to work with. At 20 ∘ C concentrated solution would be approx. 35 % with p H ≈ 12.0. The higher the temperature, the lower the solubility and the p H will be. Having 29 % stock ammonia solution, there is no way to reach p H 12.8.
WebAmmonium hydroxide is widely utilized as a leavening agent or acidity regulator in food production. It serves as a precursor to some alkyl amines and is also used in the tobacco industry for flavor enhancement and as a processing aid. During furniture making, it combines with tannic acid and is used to darken or stain wood by making it iron salts. WebAmmonium hydroxide solution with a 25% mass fraction has a melting point of 215.7 K and a boiling point of 310.8 K Its standard enthalpy of formation is -80 Kilojoules per mole.
