HNO3+Ba(OH)2

The reaction between nitric acid (HNO₃) and barium hydroxide (Ba(OH)₂) is a neutralization reaction, where an acid reacts with a base to produce a salt and water. Here’s the balanced chemical equation for the reaction:

\[ \text{2 HNO}_3 (aq) + \text{Ba(OH)}_2 (aq) \rightarrow \text{Ba(NO}_3\text{)}_2 (aq) + 2 \text{H}_2\text{O} (l) \]

In this reaction:

• Barium hydroxide, a strong base, reacts with nitric acid, a strong acid.
• The products are barium nitrate (Ba(NO₃)₂), which is a soluble salt, and water (H₂O).

This reaction typically occurs in aqueous solution, and since both reactants are strong, the reaction goes to completion, forming the products as specified.
