Most vinegars including apple cider vinegar and white distilled vinegar , are 3-5% acetic acid while cleaning vinegar can range

Answer:
- <u>Higher acidity (lower pH) making it a better cleaning solution because it will be able to kill more microorganisms</u>
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:
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.

The oxidation is occurring on Calcium ions as it release one electron and reduction will be occurring on fluorine ion as it accepts one electron.
<u>Explanation:</u>
An element will undergo oxidation and form a positive ion on releasing one or more electrons from its valence shell. While reduction is occurred in a chemical reaction, then the element will be forming a negative ion with the acceptance of one or more electrons in its valence shell.
So in the given process of calcium fluoride, the one electron from the valence shell of calcium will be released making it as ions and this is termed as oxidation process. This one electron will be getting accepted by the fluorine ion and thus it will convert to
ions. This process of acceptance of electrons is termed as reduction.
