Final answer:
The reaction of hydrochloric acid with sodium bicarbonate is ideal for titration as it allows determination of HCl concentration by neutralization. The titration curve indicates the equivalence point where equal amounts of acid and base react. Furthermore, it facilitates the analysis of solutions containing a mixture of weak and strong bases.
Step-by-step explanation:
The reaction of hydrochloric acid (HCl) with sodium bicarbonate (NaHCO₃) is useful for a titration experiment because it allows for the determination of the concentration of hydrochloric acid present. This acid-base reaction is a neutralization reaction in which sodium bicarbonate acts as a weak base and hydrochloric acid as a strong acid. The reaction produces carbon dioxide (CO₂), water (H₂O), and sodium chloride (NaCl).
Using a titration curve, it is possible to identify the equivalence point where the amount of acid equals the amount of base, typically reflected in a dramatic change in pH. This is significant because it helps to calculate the concentration of the acid or base in solution accurately. It is important to note that the mole ratio between HCl and NaOH is 1:1.
