The correct answer is because distilled water has a neutral pH=7.

Explanation:

Distilled water has a neutral pH of 7, which means that water is neither an acid nor a base. Vinegar is a dilute acid that can be further diluted with water, or it can be neutralized using a base. The term "pH" means "hydrogen potential", the more hydrogen-free ions in flotation in a solution, the more acidic it will be.

The pH of vinegar will always be kept at a lower than neutral number, no matter how diluted, because vinegar is an acid.

By adding distilled water (pH = 7) to the vinegar, it does not increase the amount of H + in the solution, so it does not affect the pH of the vinegar.

Have a nice day!
