Question 29

The equation below shows the proton transfer reaction between methylamine and the hydrogen sulfate ion in aqueous solution:

CH3NH2(aq)+HSO4−(aq)⇌CH3NH3+(aq)+SO42−(aq) \text{CH}_3\text{NH}_2(\text{aq}) + \text{HSO}_4^-(\text{aq}) \rightleftharpoons \text{CH}_3\text{NH}_3^+(\text{aq}) + \text{SO}_4^{2-}(\text{aq}) CH3​NH2​(aq)+HSO4−​(aq)⇌CH3​NH3+​(aq)+SO42−​(aq)

Which of the following represents a conjugate acid-base pair in this reaction?

CH3NH2\text{CH}_3\text{NH}_2CH3​NH2​ and HSO4−\text{HSO}_4^-HSO4−​

HSO4−\text{HSO}_4^-HSO4−​ and CH3NH3+\text{CH}_3\text{NH}_3^+CH3​NH3+​

CH3NH2\text{CH}_3\text{NH}_2CH3​NH2​ and CH3NH3+\text{CH}_3\text{NH}_3^+CH3​NH3+​

SO42−\text{SO}_4^{2-}SO42−​ and CH3NH3+\text{CH}_3\text{NH}_3^+CH3​NH3+​
