What is in vinegar?

Answer:
Vinegar has fruit in it, which is probably why you have fruit flies. Also, vinegar is acidic, meaning it contains acid. The type of acid it contains is acetic acid which releases hydrogen ions. I hope I answered your question!

Vinegar is an acidic liquid processed from the fermentation of ethanol in a process that yields its key ingredient, acetic acid (also called ethanoic acid). It also may come in a diluted form. The acetic acid concentration typically ranges from 4 to 8 percent by volume for table vinegar [1] (typically 5%) and higher concentrations for pickling (up to 18%). Natural vinegars also contain small amounts of tartaric acid, citric acid, and other acids. ( Wikipedia ).
