Sodium hydroxide solution (in water) reacts with hydrochloric acidsolution (in water) to produce sodium chloride solution and water

This is a classic example of an acid-base neutralization reaction. Here's the step-by-step process:

1. Identify the reactants: Sodium hydroxide (NaOH) is a base and hydrochloric acid (HCl) is an acid.

2. Write the chemical equation of the reaction: NaOH (aq) + HCl (aq) -> NaCl (aq) + H2O (l)

3. Balance the equation: The equation is already balanced, meaning there is the same number of each type of atom on both sides of the equation.

4. Describe the reaction: Sodium hydroxide solution reacts with hydrochloric acid solution to produce sodium chloride solution and water. This is a neutralization reaction because an acid (HCl) and a base (NaOH) are reacting to form a salt (NaCl) and water.
