Question

A salt is formed when nitric acid combines with sodium hydroxide. What ions are present in the salt that forms?

Answer 1

HNO3 + NaOH --> H2O + NaNO3
Sodium nitrate is formed, which is made of Na+ and NO3-

Answer 2

Answer: $Na^++NO_3^-$

Explanation:

It is double displacement reaction in which exchange of ions take place.

When an acid and base combines to give salt and water, the double displacement reaction is called as neutralization. the  nitric acid is a strong acid which dissociates to give $H^+$ and $NO_3^-$ ions an d sodium hydroxide is  a strong base which dissociates to give  $Na^+$ and $OH^-$ ions.

They result into formation of sodium nitrate which dissociates in water to give $Na^+$ and $NO_3^-$ ions.

$HNO_3+NaOH\rightarrow NaNO_3+H_2O$
