Reaction of ammonia

 When ammonium hydroxide (NH4OH) is added to a solution containing barium chloride (BaCl2), a noticeable reaction occurs.

1. Ammonium hydroxide, a colorless liquid with a pungent odor, is added to a solution of barium chloride.

2. Barium chloride, a white crystalline solid, is highly soluble in water.

3. As NH4OH is introduced, it dissociates into NH4+ and OH- ions, which are responsible for the reaction.

4. The OH- ions from NH4OH combine with the Ba2+ ions from BaCl2, forming a white precipitate called barium hydroxide (Ba(OH)2).

5. Barium hydroxide is sparingly soluble and appears as a cloudy or milky suspension in the solution.

6. The reaction is a double displacement reaction, where the OH- ions…

7. As a result, barium hydroxide (Ba(OH)2) and ammonium chloride (NH4Cl) are formed.

8. The ammonium chloride remains dissolved in the solution.

9. The white precipitate of barium hydroxide indicates the presence of Ba2+ ions.

10. This test is commonly used to identify the presence of barium ions in a solution.
