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:
[tex]pH=\log\dfrac{1}{[H_3O^+]}[/tex]
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.
