Question
Pick the correct answer. (What I think are the answers are bold, Ihave no idea for either (iv)) Please correct me if I amincorrect.(a) The following equilibrium occurs when hydrogen sulfate ion(HSO4-) dissociates in water:
HSO4-(aq) + H2O(l)<--> SO42-(aq) +H3O+(aq)
(i) HSO4- is a/an(acid/base).
(ii) H2O is a/an (acid/base).
(iii) SO42- is a conjugate(acid/base) and H3O+ is aconjugate (acid/base).
(iv) Dissolving HSO4- in water would givea/an (acid/base).
(b) The following equilibrium occurs when formate(CHO2-) dissociates in water:
CHO2-(aq) +H2O(l)<--> HCHO2(aq) +OH-(aq)
(i) CHO2- is a/an (acid/base).
(ii) H2O is a/an (acid/base).
(iii) HCHO2 is a conjugate (acid/base)and OH- is a conjugate (acid/base).
(iv) Dissolving CHO2- in water would give a/an(acid/base).
Explanation / Answer
(a) i) CORRECT - HSO4- acts as a protondonor ii) CORRECT - H2O acts as a proton acceptor iii) CORRECT iv) I think the answer is acid as dissolvingHSO4- resulting in the production ofH3O+ which indicate the acifity of thesolution. (b) i) CORRECT - it accept proton ii) CORRECT - water acts as proton donor iii) CORRECT iV) The answer should be base as the resulting solution containsOH-which indicates the alkaline nature of solution Hope this helps!
