Vinegar is a liquid used mostly in cooking. It can be made from wine or other liquids containing alcohol, like cider or fermented fruit juices. Ethanol is oxidized from the liquid, resulting in vinegar.
Vinegar has many different pHs depending on the type; the pH of apple cider vinegar is typically between pH 4.25 and 5.00 if undiluted while distilled vinegar has a pH of around 2.4.
