What is Bronsted Lowry acid?

A proton H+ donor.


What is Bronsted Lowry base?

A proton H+ acceptor.


What is a conjugated acid base pair?

A pair of species that differ by 1 proton (H+)


What is important about the reaction of ethanoic acid with water:
CH3COOH + H20 CH2COO- + H3O+

In the forward direction the CH3COOH donates a proton (H+) to the H2O, the Ch3COOH is an acid as it donates a proton, the H2O accepts a proton and therefore acts as a base.
In the reverse direction H30+ acts as an acid because it donates a proton to CH3COO- which accepts a proton and is a base.


In the above reaction what is the conjugate acid base pair?

CH3COOH acts as an acid and donates a proton to form its conjugate base CH3COO- and therefore CH3COOH and CH3COO- differ by 1H+ and represent a conjugate acid base pair. H20 and H3O+ are also a conjugate aid base pair.


What is amphiprotic?

A species that can donate a proton acting as an acid or accept a proton acting as a base.


What is amphoteric?

Any substance that can act as both an acid and a base.
