Question

A whit precipitate will be formed if we add ammonia solution to :

• A. $$Mg(No_3)_2$ solution$
• B. $$KNO_3$ solution$
• C. $$Alcl_3$ solution$
• D. $$Ba(NO_3)_2$ solution$

Answer 1

Answer:

$$Alcl_3$ solution$

When ammonia solution is added to AlCl3, a white precipitate of Al(OH)3 forms, indicating a chemical reaction. When ammonia solution (NH₃) is added to AlCl₃ (Aluminum chloride), a white precipitate of Al(OH)₃ (aluminum hydroxide) is formed. This occurs because ammonia provides hydroxide ions (OH⁻), which react with aluminum ions (Al³⁺) in the solution.
