When barium hydroxide (Ba(OH)2) reacts with ammonium chloride (NH4Cl), it results in the formation of barium chloride (BaCl2), water (H2O), and ammonia (NH3) gas. The reaction can be represented by the following balanced chemical equation:
Ba(OH)2 + 2NH4Cl -> BaCl2 + 2H2O + 2NH3
In this reaction, the barium hydroxide reacts with ammonium chloride in a double displacement reaction, where the hydroxide ions (OH-) from barium hydroxide combine with the ammonium ions (NH4+) from ammonium chloride. This forms water and ammonia gas as products. Meanwhile, the barium ions (Ba2+) from barium hydroxide combine with the chloride ions (Cl-) from ammonium chloride, resulting in the formation of barium chloride.
It's worth noting that both barium chloride and ammonia gas are soluble in water, while barium hydroxide and ammonium chloride are also soluble in water. Therefore, this reaction can easily take place in an aqueous solution.
Please exercise caution when working with barium hydroxide and follow appropriate safety protocols, as barium compounds can be toxic.
