Question

What happens when barium hydroxide octahydrate reacts with ammonium chloride

Answer 1

Ammonium Chloride is slightly acidic and Barium Hydroxide very basic, so you will get an acid-base reaction occurring (though both reactants are solid). ... Reaction between (barium hydroxide) Ba(OH)2 + NHCI (ammonium chloride) is a double displacement gas evolution reaction.

Hope this helps..

Answer 2

Answer:

Answer:Solid hydrated barium hydroxide is mixed with solid ammonium chloride in a beaker. An endothermic reaction takes place to produce a liquid, with the evolution of ammonia. The temperature drops dramatically to about -20 °C.
