Question

Conjugate Pairs According to the Bransted-Lowry theory, an acid is any substance (molecule or ion) that can transfer a proton (H' ion) to another substance, and a base is any substance that can accept a proton Acid-base nreactions ane protor-bansfer neactions as follows Part A The following equation shows the equilibrium in an aqueous solution of ethylamine HA + BH +A CH,NH, (aq) + H,O) C,H,NH, '(aq) + OH (aq) base acid base acid Which of the following represents a conjugate acid-base pair? Chemical species whose fommulas differ only by one proton are said to be conjugale acid- base pairs. Thus, A is the conjugate base of the of the base A Similarly, Bis the conjugate base of the acid BH and BH is the conjugate acid of the base B Strong acids have weak acids have strong corjugate basesi HA and HA is the conjugate acid View Available Hint(s) weak conjugae bases and very CH,NHy and HaO CH,NH, and OH o H,0and OH CHNH, and OH Submit Part B What is the conjugate base of HCO, Express your answer as a chemical formula View Available Hints) AE4 Submit

Answer 1

Part A → Ans - H₂o and on- Ho acts as an acid and donates a proton becoming Oh which is the conjugate base Part B 102- H2O2- acts as an wad and donates a proton becoming coz which is the conjugate base part o H₂ Poz MPO2- acts as a base accepting a proton and becoming H₂POj, a conjugate acid
