Question

Consider the statements based on the reaction given and choose the correct option.

$HN{O}_3\left(aq\right)+KOH\left(aq\right)\to KN{O}_3\left(aq\right)+H_{2}O\left(l\right)$

Statement 1: It is a double displacement reaction.
Statement 2: It is a precipitation reaction.
Statement 3: It is a neutralisation reaction.

• A. All the statements are true
• B. Statement 1 and 2 are true
• C. Statement 1 and 3 are true
• D. Statement 2 and 3 are true

Answer 1

The correct option is C Statement 1 and 3 are true

$\bullet$ A double displacement reaction is a type of reaction in which two reactants exchange ions to form two new compounds. In the given reaction, $H^{+}$ and $K^{+}$ ions interchange to form new products and hence it is a double displacement reaction.

$\bullet$ A precipitation reaction is a double displacement reaction in which a precipitate is formed. However, not all double displacement reaction involves a precipitate formation. In the given reaction, the products formed are salt and water and no precipitate is formed.

$\bullet$Additionally, the given reaction is a neutralisation reaction as $HN{O}_3$ is an acid which is neutralised by $KOH$ base to result in salt formation.
