When carbonic acid (H₂CO₃) is neutralized with potassium hydroxide (KOH), the products formed are:

* Potassium carbonate (K₂CO₃): This is the salt formed from the reaction.

* Water (H₂O): This is produced as a byproduct of the neutralization reaction.

Here's the balanced chemical equation for the reaction:

H₂CO₃ (aq) + 2KOH (aq) → K₂CO₃ (aq) + 2H₂O (l)

Explanation:

* Carbonic acid (H₂CO₃) is a weak acid, meaning it doesn't completely ionize in solution.

* Potassium hydroxide (KOH) is a strong base, meaning it completely ionizes in solution, releasing hydroxide ions (OH⁻).

* The hydroxide ions from KOH react with the hydrogen ions (H⁺) from H₂CO₃ to form water (H₂O).

* The remaining potassium ions (K⁺) and carbonate ions (CO₃²⁻) combine to form potassium carbonate (K₂CO₃).
