Answer:
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-.
