Explain acid and based according to Bronsted Lowry and theory.

According to Bronsted Lowry theory:

Acids are the substances which donate a proton.


Bases are the substances which accept a proton.


They give conjugate acid-base pair concept.



For example:



Here water (H2O) is a proton donor, hence it is acid. Acid


changes into the conjugate base by losing a proton (H+)


Ammonia (NH3) is a proton acceptor, hence it is base. Base


changes into conjugate acid by accepting a proton (H+)
