Answer
Both A and R are true and R is the correct explanation of A.
Explanation — Nitric acid reacts with alkalies like NaOH/KOH and neutralises it to form salt and water. Hence, the assertion (R) is true.
NaOH + HNO3 ⟶ NaNO3 + 2H2O
Alkalies react with acids to form salt and water. Such type of reactions are called as neutralisation reaction. Hence, the reason (R) is true.
Since, reason (R) depicts the neutralisation reaction that takes place between Nitric acid and NaOH/KOH, it is the correct explanation of assertion (A).
