Identify the Brønsted-Lowry acid, the Brønsted-Lowry base, the conjugate acid, and the conjugate base in each reaction:

(a) C5H5N (aq) + H2O (l) →C5H5NH + (aq) + OH - (aq)

(b) HNO3 (aq) + H2O (l) →H3O + (aq) + NO3 - (aq)

C5H5N is the base and C5H5NH + is the conjugate acid

H2O is the acid and OH - is the conjugate base

Explanation:

Hydrogen + is also called a proton

C5H5N is the base because it receives the proton (H+) and C5H5NH + is its conjugate acid

H2O is the acid because it gives up the proton and OH - is the conjugate base because it is capable of receiving the proton

Answer:

HNO3 is the acid and NO3 - is the conjugate base

H2O is the base and H3O + is the conjugate acid

Explanation

HNO3 is the acid and NO3 - is its conjugate base, capable of receiving a proton

H2O is the base because it receives the proton and H3O + is a conjugate acid capable of giving up the proton.
