Question

Why adding distilled water to the vinegar sample prior to beginning the titration does not affect the results of your determination of the molarity of ch3cooh in your vinegar sample

Answer 1

Answer:

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!
