Molar Mass - molecular weight is 35.05 g/mol. Specific gravity - It is typically 0.9 and actually depends on the strength of the solution.īoiling point - 38☌ and 100☌ based on the concentration Physical Properties of Ammonium Hydroxide: The Ammonium hydroxide is prepared by saturating water with gaseous ammonia. In the common representation used for organic molecules, its chemical structure can be written as below. The compound structure is formed by one hydroxide anion (OH - ) and one ammonium cation NH 4 + which share an ionic bond. The chemical is also known by many other names like:Ĭhemical Formula for Ammonium Hydroxide: NH 4 OH or H 5 NOĪppearance: It appears as a colorless liquid Įxcept in highly dilute solutions, the ions N H 4 + and O H - do not account for a significant fraction of the total volume of ammonia. The ammonium hydroxide is an alkali with a composition of O H - ions it is not possible to isolate samples of N H 4 O H. When Ammonia dissolves in water it results in the formation of ammonia hydroxide.Īmmonium hydroxide is a solution where ammonia is mixed in water. Do not forget to refer to the frequently asked questions at the end for clearing your doubts if you incur any while going through the topic.Īmmonia Hydroxide is a colourless liquid that comes under a class of substance known as costex. In this article, we will discuss Ammonium hydroxide, its formula and structure use and properties.
