Examples of buffered solutions
WebBuffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical applications. In nature, there are many living systems that use … WebExamples of buffer solutions. Let’s now look at an example of a buffer solution in action. A typical buffer solution can be made from ethanoic acid and sodium ethanoate. The ethanoic acid partially dissociates in solution: CH 3 COOH ( aq) ⇌ CH 3 COO - ( aq) + H + ( aq) The sodium ethanoate fully ionises in solution:
