← ScienceWhich consequence results when deionized water contacts powdered aluminium chloride?
A)Formation of bridging hydroxyl complexes
B)Precipitation of aluminium hydroxide✓
C)Suppression of ionic transport
D)Passivation via aluminium oxide layer
💡 Explanation
Aluminium chloride is an ionic compound and hygroscopic; it undergoes hydrolysis in water forming hydrochloric acid and aluminium hydroxide due to the hydroxide ions that displace chloride ions. Therefore, a precipitate forms rather than passivation because acidity accelerates the break down of chloride structures.
