The word vinegar itself derives originally from the Latin , vinum aegrum meaning “feeble wine”. In fact, when a wine has “gone off” and has acquired a sour taste, this is due to the oxidation of the ethanol in the wine to acetic acid.

WebA buffer solution is one which resists changes in pH when small amounts of acid or alkali is added to it. It plays an important role in chemical processes where it is essential that a fairly constant pH is maintained. Buffer solutions could be classified into two types, namely acidic buffer and basic buffer solutions.
