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.
Not so. All citrus has ascorbic acid.
Junior high science class strikes again!!
Actually, citrus fruit has citric acid. Amazing! Three (3) carboxylic
acid moieties per molecule, hence it is capable of chelating (capturing)
calcium. That is the basis for use of citric acid (or trisodium citrate)
as anticoagulants (preventing platelet activation and blood clotting).
