Question

Most vinegars including apple cider vinegar and white distilled vinegar , are 3-5% acetic acid while cleaning vinegar can range from 6 15% acetic acid. What advantage does this give a cleaning solution?

Answer 1

Answer:

• Higher acidity (lower pH)  making it a better cleaning solution because it will be able to kill more microorganisms

Explanation:

The higher the percentage of the vinegar solution, the higher the molar concentration of hydrodium ions, [H₃O⁺].

pH is a measure of the concentration of H₃O⁺ ions:

       $pH=\log\dfrac{1}{[H_3O^+]}$

The lower the pH the more acidic the solution.

Thus, the higher the percentage of vinegar, the higher  [H₃O⁺], the lower the pH, and the more acidic the solution.

The feature that makes vinegar a good cleaning agent is its acidity: high acidity environments are inhospitable for many microorganisms.

Thus, the advantage of a vinegar with 6 - 15% acetic acid is its higher acidity (lower pH), which makes it more suitable to kill more microorganisms.

Answer 2

Answer: B.

A cleaning solution made with cleaning vinegar would be stronger with a higher concentration of acetic acid.
