2. HOA2+H20 . → H3O+ + OA-CIn this reaction:(i) OA c is the conjugate base of H2O(ii)OA-c is the conjugate base of HOAc (iii) H3O+ is theсconjugate base of HOA.(iv) H3O+ is the conjugate acid of H2O(a) i(b) ii (c) iii (d) iv (e) none

Answer
(ii) and (iv)
Explanation
In the given reaction,
HOAc is the acid because it donates its proton to H2O to become a conjugate base OA-c.
H₂O acts as the base by accepting the proton to become a conjugate acid H₃O⁺
Hence,
(i) OA-c is the conjugate base of H₂O. NO.
OA-c is the conjugate base of HOAc
(ii) OA-c is the conjugate base of HOAc. YES.
(iii) H₃O⁺ is the conjugate base of HOAc. NO.
H₃O⁺ is the conjugate acid of H₂O.
(iv) H₃O⁺ is the conjugate acid of H₂O. YES.
The correct statements that are true about the given reaction are:
(ii) and (iv)
