Answer: [tex]KNO_3[/tex] and [tex]H_2O[/tex]
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 [tex]H^+[/tex] ions and potassium hydroxide is the base as it gives [tex]OH^-[/tex] ions. When nitric acid react with potassium hydroxide base, potassium nitrate [tex](KNO_3)[/tex] is formed as a salt and water [tex](H_2O)[/tex] is formed.
The balanced reaction will be,
[tex]HNO_3(aq)+KOH(aq)\rightarrow KNO_3(aq)+H_2O(l)[/tex]
