Ethanoic acid solution, properties

Ask students to test the properties of the ethanoic acid solution. To do this, put 1-2cm depth acid in each of four test tubes. Then test the samples as follows. 

We see how solvated protons impart the subjective impression of a sour, bitter flavour to the ethanoic acid in vinegar. In fact, not only the sour flavour, but also the majority of the properties we typically associate with an acid (see Table 6.1) can be attributed to an acidic material forming one or more solvated protons H+(aq) in solution. 

Common acids found in the laboratory include ethanoic acid, CH3COOH(aq), sulfuric acid, H2S04(aq), hydrochloric acid, HCl(aq), and nitric acid, HlSI03(aq). Acids are a group of compounds that exhibit the following properties when dissolved in water to form a dilute solution.
