Question

Complete and balance the equation

$\mathrm{NaOH}+\mathrm{HCl}\to$

Answer 1

Step 1: When Sodium hydroxide $\left(\mathrm{NaOH}\right)$ which is a base reacts with an acid i.e., Hydrochloric acid $\left(\mathrm{HCl}\right)$, then it gives Sodium chloride $\left(\mathrm{NaCl}\right)$ as salt and water$\left({\mathrm{H}}_2\mathrm{O}\right)$. This is referred to as a neutralization reaction.

$\mathrm{NaOH}+\mathrm{HCl}\to \mathrm{NaCl}+{\mathrm{H}}_2\mathrm{O}$

Step 2: Balancing the chemical equation step by step as:

1. Count the number of atoms on both the reactant and product sides.

Reactant	Product
Na - 1	Na - 1
O - 1	O - 1
H - 2	H - 2
Cl - 1	Cl - 1

Here the atoms of Sodium, Chlorine, Oxygen, and Hydrogen are balanced on both sides. Thus, the given chemical equation is balanced.

Step 3: Therefore, the balanced chemical equation is given as;

$\mathrm{NaOH}+\mathrm{HCl}\to \mathrm{NaCl}+{\mathrm{H}}_2\mathrm{O}$
