According to the Brønsted-Lowry theory, which of the following is a conjugate acid-base pair?
A
HCl and NaOH
B
H2O and OH-
C
H3O+ and OH-
D
HCl and Cl-
correct option: c
In the Brønsted-Lowry theory, a conjugate acid-base pair consists of an acid and a base that are related by the transfer of a proton. In this case, H3O+ (hydronium ion) acts as the conjugate acid, donating a proton, while OH- (hydroxide ion) acts as the conjugate base, accepting the proton.
