Answer: \(KNO_3\) and \(H_2O\)
Explanation: When an acid reacts with the base then it undergoes neutralization to form salt and water.
In the given case nitric acid is the acid as it donates \(H^+\) ions and potassium hydroxide is the base as it gives \(OH^-\) ions. When nitric acid react with potassium hydroxide base, potassium nitrate \((KNO_3)\) is formed as a salt and water \((H_2O)\) is formed.
The balanced reaction will be,
\(HNO_3(aq)+KOH(aq)\rightarrow KNO_3(aq)+H_2O(l)\)
