A salt is formed when nitric acid (HNO3) combines with sodium hydroxide (NaOH). What ions are present i the salt that forms?

Na + and NO₃-

Explanation:

The salt that forms becomes sodium nitrate. Separating each compound, we get that hydrogen's charge is +, nitrate's charge is -, hydroxide's charge is -, and sodium's charge is +. The nitrate and the sodium switch partners in the double replacement acid-base (neutralization) reaction.

HNO₃ + NaOH ⇒ NaNO₃ + H₂O

H + NO₃ - + Na+OH - ⇒ Na + NO₃ - + 2H+O⁻²

Therefore, the ions that are present in the salt that forms is Na + and NO₃-.
