Here's why:
* Neutralization: Neutralization is a chemical reaction where an acid and a base react to form salt and water.
* pH Scale: The pH scale measures the acidity or alkalinity of a solution.
* pH 7 is neutral.
* pH below 7 is acidic.
* pH above 7 is alkaline (basic).
* Sodium Hydroxide (NaOH): This is a strong base.
* Acid: When a strong acid like hydrochloric acid (HCl) is added to the sodium hydroxide solution, the hydrogen ions (H+) from the acid react with the hydroxide ions (OH-) from the base to form water (H2O). This reaction continues until all the hydroxide ions are consumed.
Therefore, at the point of neutralization, the solution will have a pH of 7, indicating it is neutral.
