  2. Barium hydroxide - Wikipedia

    en.wikipedia.org/wiki/Barium_hydroxide

    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.

  3. Ammonium chloride - Wikipedia

    en.wikipedia.org/wiki/Ammonium_chloride

    Ammonium chloride is an inorganic chemical compound with the chemical formula N H 4 Cl, ... such as its reaction with barium hydroxide and its dissolving in water.

  4. Solubility chart - Wikipedia

    en.wikipedia.org/wiki/Solubility_chart

    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.

  7. Endothermic process - Wikipedia

    en.wikipedia.org/wiki/Endothermic_process

    The formation of barium thiocyanate from ammonium thiocyanate and barium hydroxide is so endothermic that it can freeze a beaker to wet styrofoam. Due to bonds breaking and forming during various processes (changes in state, chemical reactions), there is usually a change in energy.

  8. Base (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Base_(chemistry)

    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:
