Can act as either an acid or a base

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. WebMar 13, 2024 · In the preceding paragraphs we saw that water can function as either an acid or a base, depending on the nature of the solute dissolved in it. In fact, in pure water or in any aqueous solution, water acts both as an acid and a base.

10.3 Water: Both an Acid and a Base

WebA base is a molecule or ion able to accept a hydrogen ion from an acid. Acidic substances are usually identified by their sour taste. An acid is basically a molecule which can donate an H + ion and can remain energetically favourable after a loss of H +. Acids are known to turn blue litmus red. WebMany chemistry texts incorrectly use this term to mean that a substance can act as either an acid or a base. Arrhenius Model Arrhenius proposed that acids are substances that produce protons (H +) in aqueous solution, whereas bases produce hydroxide ions (OH - ) in aqueous solution.
