buffer solution
Explanation:
Uma solução tampão (ou simplesmente tampão) é uma solução que sofre apenas pequena variação de pH quando a ela são adicionados íons ou H+ ou OH-. É uma solução que contém um ácido e sua base conjugada, em concentrações aproximadamente iguais. Um bom exemplo é uma solução de ácido. (http://br.geocities.com/chemicalnet/quali/efeitotampao.htm)

Buffer, pH Buffer, Buffer Solution (Chemistry)
A solution that can maintain its pH value with little change when acids or bases are added to it. Buffer solutions are usually prepared as mixtures of a weak acid with its own salt or mixtures of salts of weak acids. For example, a 50:50 mixture of 1 M acetic acid and 1 M sodium acetate buffers pH around 4.7.
