Svante Arrheniusprovided the first and most basic definition of acids and bases in 1884. Arrhenius acids are compounds that release hydrogen ions (H+), while Arrhenius bases are those that release hydroxyl ions (OH-). The reaction of such acids and bases leads to salts and water. However, it is limited. Arrhenius Reactions The general equation of a...
The limitations of Arrhenius's theory are addressed in Brønsted-Lowry definitions. Brønsted-Lowry acids are proton donors, while Brønsted-Lowry bases are proton acceptors. In this theory, a proton is defined as a single hydrogen ion (H+), and amphoteric substances act as both acids and bases. The definition of Brønsted-Lowry may apply to the Arrhen...
While the Brønsted-Lowry theory is more inclusive than the Arrhenius, it still has limitations. It cannot explain why compounds like boron trifluoride (BF3) or aluminum (III) chloride (AlCl3) can act as acids without protons. It also does not cover reactions between acid and base oxides.
Unlike the previous theories, Lewis acid and base definitions do not involve the exchange of ions like H+. A Lewis acid accepts electron pairs while a Lewis base donates them. There is no need for the transfer of ions like H+. Thus, it considers proton-less compounds like boron trifluoride (BF3) to be acids because they accept electron pairs. The L...
The best way to illustrate the Lewis theory is through the reaction of boron trifluoride with ammonia: BF3 + NH3 → H3NBF3 In this reaction, BF3 receives electron pairs from NH3. It results in a compound with a coordinate covalent bond. The Lewis theory also explains the formation of complex ionsor coordination compounds. It can involve metals, like...
Three different definitions of acids and bases are based on Arrhenius, Brønsted-Lowry, and Lewis's theories. Each theory becomes increasingly comprehensive than the other. The most comprehensive one, Lewis's theory, allows scientists to identify substances better and thereby predict reactions.
For example, the –COOH group is referred to as a carboxylic acid. This functional group is the source of acidity in organic acids. Another functional group, the amine, has a nitrogen with a free pair of electrons and behaves as a base. pH is a logarithmic unit of concentration.
