Explanation:
When an acid reacts with a base then it results in the formation of salt and water.
\(HNO_{3}\) is an acid and \(NH_{4}OH\) is a base thus, when we dissolve ammonium hydroxide in nitric acid then it results in the formation of ammonium nitrate and water.
The reaction is as follows.
\(NH_{4}OH + HNO_{3} \rightarrow NH_{4}NO_{3} + H_{2}O\)
Hence, there will be formation of ammonium nitrate \((NH_{4}NO_{3})\) salt.
