Reactions of barium hydroxide with ammonium salts are strongly endothermic. The reaction of barium hydroxide octahydrate with ammonium chloride [18] [19] or [20] ammonium thiocyanate [20] [21] is often used as a classroom chemistry demonstration, producing temperatures cold enough to freeze water and enough water to dissolve the resulting mixture.
Ammonium chloride is an inorganic chemical compound with the chemical formula N H 4 Cl, also written as ... such as its reaction with barium hydroxide and its ...
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

Ammonia fumes from aqueous ammonium hydroxide (in test tube) reacting with hydrochloric acid (in beaker) to produce ammonium chloride (white smoke). Bases react with acids to neutralize each other at a fast rate both in water and in alcohol. [7] When dissolved in water, the strong base sodium hydroxide ionizes into hydroxide and sodium ions:

Barium chloride is an inorganic compound with the formula Ba Cl 2. It is one of the most common water-soluble salts of barium . Like most other water-soluble barium salts, it is a white powder, highly toxic, and imparts a yellow-green coloration to a flame.
