Paragraph: A titration curve graph of pH as a function of the volume of titrant, displays in detail how the pH changes over the course of an acid-base titration. Significantly, the pH changes most rapidly near the equivalence point. The exact shape of a titration curve depends on the relative strengths of acids and bases. Examine the titration curve below: Question: The pH at equivalence point is

Options

  1. A11
  2. B7
  3. C3
  4. D2

Correct answer

B. 7

Step-by-step solution

Since curve is given for strong acid and strong base hence, pH at the end point is 7 .
