Interpretation:The direction of equilibrium that is favoredshould be identified.
Concept introduction:In accordance with Bronsted definition an acid can act as a proton donor and a base can act as a proton acceptor. Thus in a typical acid-base reaction, the fundamental principle is a lone pair of base reaches out for an acidic proton. Similar curved arrows are used to show the movement of electrons. After deprotonation, the species left with a negative charge is referred as the conjugate base of acid while the other with a positive charge is termed conjugate acid of given base. For example,
The strength of various conjugate acid-base pairs varies inversely to one another; the strong acid has a weak conjugate base and the strong base has weak conjugate acid and vice-versa.
