What is conjugate acid base pair
Answers
• A conjugate acid, within the Brønsted–Lowry acid–base theory, is a species formed by the reception of a proton (H+) by a base—in other words, it is a base with a hydrogen ion added to it.
• On the other hand, a conjugate base is what is left over after an acid has donated a proton during a chemical reaction.
In a conjugate acid base pair, a conjugate acid contains one more hydrogen atom and one more positive charge then the conjugate Acid which formed it.
The conjugate base in that acid base pair has One Less hydrogen atom and less positive charge or more negative charge as compared to the conjugate Acid which formed it.
Every acid has a conjugate base and every base has a conjugate acid and if we put it together we get to know that whenever they react the acid donates H positive ion and forms a conjugate acid base pair.
For example :
NH3 + H2O --> NH4+ + OH-
In this equation ammonia is the conjugate base because it accepts a H positive ion to become its conjucate acid.
