Compounds That Could Be Either Acids or Bases - Purdue University
WebCompounds That Could Be Either Acids or Bases. Sometimes the hardest part of a calculation is deciding whether the compound is an acid or a base. Consider sodium bicarbonate, for example, which dissolves in water to give the bicarbonate ion. In theory, the bicarbonate ion can act as both a Brnsted acid and a Brnsted base toward water. WebA water molecule can act as an acid or a base even in a sample of pure water. About 6 in every 100 million (6 in 10 8) water molecules undergo the following reaction: H2O (ℓ) + H2O (ℓ) → H3O+(aq) + OH−(aq) This process is called the autoionization of water ( Figure 10.2 "Autoionization") and occurs in every sample of water, whether it ...
