Introduction Vinegar is a liquid produced from the fermentation of ethanol in a process that yields its key ingredient, acetic acid. The acetic acid concentration ranges typically from 4 to 8 percent by volume for table vinegar [1] (typically 5%) and higher concentrations for pickling (up to 18%).
Vinegar is essentially a solution of acetic acid ( HC 2 H 3 O 2) in water. The concentration of acetic acid in vinegar may be expressed as a molarity (in mol/L): (11.1) Molarity = Moles of Acetic Acid Volume of Vinegar (in L) or as a mass percent. (11.2) Mass % = ( Mass of Acetic Acid Mass of Vinegar) × 100 %.
