The two products that are formed when a solution of HNO3 and a solution of NaOH react are water and?
Naily [24]

Answer:

NaNO3

Explanation:

Hello,

In this case, the required reaction is an acid-base neutralization reaction which is said to be:

HNO_3+NaOH\rightarrow NaNO_3+H_2O

There, we see that the sodium displaced the hydrogen in the nitric acid to form sodium nitrate a very used salt in the industry, so, as a result of that displacement, water is formed as the secondary neutralization product. For the above mentioned, answer is NaNO3 .

Best regards.
