What are the products when potassium hydroxide reacts with hydrochloric acid?

Explanation:
Acid–base neutralization: a strong acid reacts with a strong base to form a salt and water. Potassium hydroxide provides OH− and hydrochloric acid provides H+. They combine to make water, while potassium ions (K+) and chloride ions (Cl−) pair to form potassium chloride, the salt. The balanced reaction is KOH + HCl → KCl + H2O. In ion terms, H+ and OH− unite to form H2O, and the remaining ions K+ and Cl− form the salt in solution. This pattern—salt plus water—fits perfectly for this reaction. The other options would require different reactants or conditions to produce oxides, sulfates, or carbonates, which aren’t produced here.
