Final answer:
The net ionic equation for hydrochloric acid dissolving aluminum hydroxide is Al(OH)3(s) + 3 H+(aq) → Al3+(aq) + 3 H2O(l), showing the dissolution of solid aluminum hydroxide into soluble aluminum ions and water.
Step-by-step explanation:
The net ionic equation for the reaction where hydrochloric acid (HCl) dissolves solid aluminum hydroxide (Al(OH)3) involves the reaction of aluminum hydroxide with hydrogen ions (H+) to form aluminum ions (Al3+) and water (H2O). In an acidic solution, aluminum hydroxide reacts with hydronium ions (H3O+), but for the purpose of the net ionic equation, we can consider the reaction with H+ as it is more common to show the dissociation of acids to H+. Here is how we can represent the net ionic equation:
Net Ionic Equation:
Al(OH)3(s) + 3 H+(aq) → Al3+(aq) + 3 H2O(l)
In this reaction, the aluminum hydroxide solid dissolves by reacting with hydrogen ions to form soluble aluminum ions and water. This is different from the complete dissociation of strong acids or bases in water. The formation of the soluble ion [Al(H2O)6]3+ from aluminum chloride in water is another reaction that shows how aluminum can behave in acidic solutions.
