Identify the type of reaction occurring between potassium hydroxide (KOH) and hydrochloric acid (HCl). This is an acid-base neutralization reaction.
Write the balanced chemical equation for the reaction: \(\mathrm{KOH + HCl \rightarrow ?}\).
Recall that in an acid-base neutralization, the hydroxide ion (\(\mathrm{OH^-}\)) from the base reacts with the hydrogen ion (\(\mathrm{H^+}\)) from the acid to form water (\(\mathrm{H_2O}\)).
Combine the potassium ion (\(\mathrm{K^+}\)) from KOH with the chloride ion (\(\mathrm{Cl^-}\)) from HCl to form potassium chloride (\(\mathrm{KCl}\)).
Thus, the products of the reaction are potassium chloride (\(\mathrm{KCl}\)) and water (\(\mathrm{H_2O}\)), confirming the correct answer.
