Answer is D. HNO3 + NaOH ---> NaNO3 + H2O
Explanation:
The reaction of Nitric acid and Sodium hydroxide represents a net ionic equation involving a strong acid and strong base. Strong acids and strong bases are considered strong electrolytes and will dissociate completely. This means that we will split them apart in the net ionic equation.
HNO3 + NaOH = NaNO3 + H2O is a neutralization reaction (also a double displacement reaction). The strong acid (HNO3) and strong base react to produce a salt (NaNO3) and water (H2O).
