Final answer:
When HNO₃ and NaOH react, the two products formed are water (H₂O) and sodium nitrate (NaNO₃), which is a typical acid-base neutralization reaction.
Step-by-step explanation:
When an aqueous solution of HNO₃ (nitric acid) reacts with an aqueous solution of NaOH (sodium hydroxide), a neutralization reaction occurs. The two products of this reaction are water (H₂O) and sodium nitrate (NaNO₃). Therefore, the correct answer is option 1) Water and sodium nitrate. This is a classical example of an acid-base reaction, where the hydrogen ion (H+) from the acid combines with the hydroxide ion (OH⁻) from the base to form water, while the remaining ions (Na+ and NO₃⁻) form the salt sodium nitrate.
