The reaction of aluminum (Al) with potassium hydroxide (KOH) produces potassium aluminate (KAlO₂), hydrogen gas (H₂), and water (H₂O).

Here's the balanced chemical equation:

2 Al + 2 KOH + 6 H₂O → 2 KAlO₂ + 3 H₂ ↑

Explanation:

* Aluminum (Al) is a reactive metal.

* Potassium hydroxide (KOH) is a strong base.

* In the presence of water, the reaction occurs.

* The aluminum reacts with the hydroxide ions (OH-) from KOH to form potassium aluminate (KAlO₂).

* The reaction also releases hydrogen gas (H₂), which is why you see bubbles forming.

Key points:

* This reaction is an example of a displacement reaction.

* The reaction is exothermic, meaning it releases heat.

* The reaction is used in the commercial production of aluminum hydroxide (Al(OH)₃).

* The reaction is also used in the cleaning of aluminum surfaces because it removes the oxide layer that forms on aluminum.

Safety:

* This reaction is highly exothermic, so handle it with caution.

* Wear appropriate safety gear, including gloves and eye protection.

* Work in a well-ventilated area.
