The Acid-Base Concept According to Brpnsted and Lowry

2 The Acid-Base Concept According to Brpnsted and Lowry 

According to Johannes Nicolaus Br0nsted and Thomas Lowry, an acid is a substance or more generally a type of particle (be it neutral or ionic) that tends to release protons p (H ions). It represents a proton donor for which we will use the abbreviations HA or BH ,  

The residual left over from separation is called the corresponding or conjugated base. The base abbreviated with A or BH acts as proton acceptor. For general purposes, it is more convenient to use symbols without charge numbers. We will use the abbreviation Ad for the acid (from the Latin acidum) and Bs for the base [(from the Greek pdoi (basis)]  

Ad and Bs form an acid-base pair abbreviated by Ad/Bs. Vp describes the proticity. If Vp = 1, one speaks of a monoprotic acid-base pair. However, if Vp 1, it is called polyprotic. Simple examples for monoprotic pairs are HCl/CP and H30 /H20  

In the first case the neutral acid hydrogen chloride HCl tends to release a proton by forming the anionic base Cl in the second the cationic acid H30 does the same under formation of the neutral base H2O.
