Step 1
Identify the correct titration curve
Answer
The titration of a strong acid (HCl) with a strong base (NaOH) typically results in a sharp increase in pH around the equivalence point. In this case, as NaOH is added to the HCl solution, the pH will rise from a low value and culminate in a steep upward curve. The correct curve will show a significant change around the point where all HCl has reacted with NaOH, which is around 10 mL of NaOH added in this scenario. The curve that represents this behavior is option D.
