Worked Solution & Example Answer:Which of the following equations best represents the reaction described by the titration curve? A - HSC - SSCE Chemistry - Question 6 - 2019 - Paper 1
Step 1
Identify the correct chemical reaction
Answer
In this case, we are considering a titration curve that typically involves an acid-base neutralization reaction. The titration curve suggests the equivalence point between an acid and a base. Among the choices, option A (NH₃(aq) + HCl(aq) → NH₄Cl(aq)) represents the neutralization of ammonia, a weak base, with hydrochloric acid, a strong acid. Hence, it reflects a typical reaction observed on a titration curve involving the transition of a weak base to its conjugate acid.
