The titration curve above could belong to which of the following acid-base pairs ?

a) CH3COOH (aq) and NaOH (aq)
b) HCl (aq) and NH3(aq)
c) CH3COOH (aq) and NH3 (aq)
d) HClO4 (aq) and KOH (aq)
e) CH3CH2COOH (aq) and KOH (aq)

1 answer

Based on the titration curve, the equivalence point is around pH 7, indicating a neutral solution. This suggests that the acid-base pair involves a strong acid and a strong base.

Among the given options, the only pair with a strong acid and strong base is option a) CH3COOH (aq) and NaOH (aq).
