Question

Identify the reactants in the chemical equation given below.
$\text{KOH(aq)}+{\text{HNO}}_3\text{(aq)}\to {\text{H}}_2\text{O(l)}+{\text{KNO}}_3\text{(aq)}$

• A. ${\text{HNO}}_3$, ${\text{H}}_2\text{O}$
• B. ${\text{H}}_2\text{O}$, ${\text{KNO}}_3$
• C. ${\text{KNO}}_3$, $\text{KOH}$
• D. $\text{KOH}$, ${\text{HNO}}_3$

Answer 1

The correct option is D $\text{KOH}$, ${\text{HNO}}_3$

In a chemical equation, the molecules which lie to the left side of the arrow are the reactants and those which lie to the right side are products.

The reactants for the given reaction are $\text{KOH}$, ${\text{HNO}}_3$. These reactants react chemically to produce the products ${\text{H}}_2\text{O}$, ${\text{KNO}}_3$.
