Hmmm,
Organic vinegar such as apple cider vinegar is not acidic!


Well, if it isn't acidic, then it isn't vinegar. *Vinegar is a weak
(~ 5%) solution of acetic acid in water. *Some types may have various
"flavourings" in addition, but it is the acid that makes it vinegar.

Hmmm,
When you have a heart burn due to too much stomach acid; acid refulux,
take some apple cider vinegar what happens? No heart burn! You can
tell from taste whether it is acidic or alkaline. Another example?
Orange is acidic, lemon is not.

Vinegar is acidic. *Try testing with litmus paper. Or bicarbonate of soda.

Common sense prevails.

Vinegar is not a pure substance and thus has no specific chemical
formula. Vinegar is mainly water (H2O), but is also comprised of
acetic acidic (the carboxylic acid which gives vinegar its pungent/
sour smell). Acetic acid's formula is CH3COOH. Vinegar is a liquid
produced by the fermentation of alcohol into acetic acid as well as
other fermentation by-products. The acetic acid concentration ranges
typically from 4 to 8 percent by volume for table vinegar (typically
5%) and higher concentrations for pickling (up to 18%) although in
some countries the minimum strength may be less. Natural vinegars also
contain smaller amounts of tartaric acid, citric acid, and other
acids.
