Final answer:
When silver chloride reacts with magnesium hydroxide, a precipitate of magnesium chloride is formed.
Step-by-step explanation:
When silver chloride (AgCl) reacts with magnesium hydroxide (Mg(OH)2), magnesium displaces silver to form magnesium chloride (MgCl₂) and water (H₂O).
The balanced chemical equation for the reaction is:
AgCl + Mg(OH)2 → MgCl₂ + H₂O
In this reaction, a precipitate is formed when silver chloride reacts with magnesium hydroxide. The precipitate is magnesium chloride (MgCl₂), which is a white solid.
