20.1 : Bronsted-Lowry acids and bases

key terms:

Bronsted-lowry acid is a proton donor

Bronsted-lowry base is a proton acceptor

Conjugate acid-base pair: contains 2 species that can be interconverted by transfer of a proton (related to eachother by the gain or loss of a single proton)

Conjugate acid-base pairs

definition- contains 2 species that can be interconverted by transfer of a proton (related to each other by the gain or loss of a single proton)

example:

even through the equilibrium sign is shown HCl is still a strong acid

example: HCl + H₂O ⇌ H₃O⁺ + Cl⁻

HCl and Cl^- act as an acid and base pair as they differ by H+ (called acid 1 and base 1)

H2O and H3O+ act as the 2nd acid and base pair (called acid 2 and base 2)
