Which combination of reactants would result in a neutralization reaction with sodium nitrate, NaNO3, as one of the products?
(A) Mg(NO3)2 + NaOH
(B) HNO, + NaOH
(C) CH4OH + NaOH
(D) HNO3 + NaCl

(B) HNO3 + NaOH

Explanation:

Hello,

In this case, for the production of sodium nitrate a substance having the sodium as a cation should react with another substance having the nitrate anion. Moreover, neutralization reactions are carried out when bases react with acids, such is the case of nitric acid and sodium hydroxide:

Thus, the answer is (B) HNO3 + NaOH  as the other options involve salts rather than acids or bases as starting reactants.
