Question

What are the products of the acid-base reaction between HNO3 and NaOH? A. H2O and NaNO3 B. NaH and NO3OH C. HNOH and NaO3 D. NaOH and HNO3

Answer 1

Answer:- A. $H_2O$ and $NaNO_3$

Explanations:- In general, $acid+base\rightarrow salt+water$

In acid-base reaction the acid gives hydrogen ion and the base gives hydroxide ion and these ions combine to form water. Rest of the ions from acid and base combine to form the salt.

Nitric acid breaks to give hydrogen ion and nitrate ion. Similarly, NaOH breaks to give sodium ion and hydroxide ion. Since, hydrogen ion and hydroxide ions form water, the sodium ion and nitrate ion forms the salt, sodium nitrate.

The reaction is shown as:

$HNO_3(aq)+NaOH(aq)\rightarrow NaNO_3(aq)+H_2O(l)$

So, the right choice is A.
