A grayscale diagram showing a legend at the top and two side-by-side rectangular beakers below. The legend defines: a small open white circle represents \(\text{H}^+\); a large solid black circle represents \(\text{X}^-\); a large gray circle represents \(\text{Y}^-\); and a diatomic pair consisting of a small open white circle touching a large gray circle represents an intact \(\text{HY}\) molecule. The left beaker, labeled 'Beaker 1: \(\text{HX}\)', contains exactly 6 separate small open white circles and exactly 6 separate large solid black circles evenly dispersed throughout the liquid volume. The right beaker, labeled 'Beaker 2: \(\text{HY}\)', contains exactly 5 intact diatomic pairs, exactly 1 separate small open white circle, and exactly 1 separate large gray circle evenly dispersed throughout the liquid volume. No other particles, labels, text, or annotations appear.
Particulate representations of equal volumes of equimolar aqueous solutions of \(\text{HX}\) and \(\text{HY}\).
The particulate diagrams above represent equal volumes of two aqueous acid solutions, \(\text{HX}\) and \(\text{HY}\), prepared at the same initial concentration. Water molecules are omitted for clarity. Equal-volume samples of each solution are titrated to the equivalence point with a standard \(0.10 \text{ M } \text{NaOH(aq)}\) solution. Which of the following statements correctly compares the two solutions?
