Equal volumes of two monoprotic acid solutions (A and B) are titrated with identical NaOH solutions. The volume to reach the equivalence point for solution A is twice the volume required to reach the equivalence point for solution B, and the pH at the equivalence point of solution A is higher than the pH at the equivalence point for solution B. Which statement is true?
A) The acid in solution A is less concentrated than in solution B and is also a weaker acid than that in solution B.
B) The acid in solution A is more concentrated than in solution B and is also a stronger acid than that in solution B.
C) The acid in solution A is less concentrated than in solution B and is also a stronger acid than that in solution B.
D) The acid in solution A is more concentrated than in solution B and is also a weaker acid than that in solution B.
