Ethanoic add

When a small amount of a strong acid is added is added to the solution containing the buffer, there is an excess of H+ ions which upsets the position of the equilibrium in (1) and, in accordance with Le Chatelier s Principle, causes a shift to the left in order to remove those ions. A weak acid such as ethanoic can only remove so many H" ions by shifting its equilibrium position the addition of an ionic salt to a buffer solution, in this case sodium ethanoate (2), produces many more ethanoate ions which can then combine with any excess H+ ions [not removed by (1)]. This forms the weak ethanoic add, and so restores the pH of the solution. 

The complexes cw-A[CrCl4 MeCN)2] and A2[CrCl5(MeCN)] (A = quinolinium, NEtJ or pyridinium) have been prepared by heating the corresponding ethanoic add complexes (rare examples of coordinated MeC02H) in ethanenitrile (Scheme 92). ... 

In a second step, the phenoxy ethanoic add reacts with methanal in the presence of hydrochloric acid, yielding a modified phenol methanal oligomer with an average molecular wdght between 600-800 g mole, as determined by vapor-pressure osmometry.

But there are some acids which are not so corrosive, even when concentrated. They are called weak acids. Ethanoic add is one example. Vinegar contains some ethanoic add.
