A rectangular box represents a closed container. A legend at the top right maps: solid black circle = \(\text{Ag}^+\), open white circle with black outline = \(\text{Cl}^-\). The bottom third of the box contains an ordered lattice of 16 particles arranged in a 4-by-4 grid with alternating solid black circles and open white circles. Along the top surface of this lattice, 1 solid black circle and 1 open white circle each have a vertical arrow pointing upward into the solution above. Directly above the lattice surface, 1 solid black circle and 1 open white circle each have an identical vertical arrow pointing downward toward the lattice. The upper two-thirds of the box contains 4 solid black circles and 4 open white circles evenly dispersed in the open space. No other particles, arrows, labels, or annotations appear.
Particulate representation of \(\text{AgCl(s)}\) in contact with its saturated solution at \(298 \text{ K}\).
A saturated aqueous solution of silver chloride, \(\text{AgCl}\), is in contact with undissolved \(\text{AgCl(s)}\) at a constant temperature of \(298 \text{ K}\), as represented in the particulate diagram below.

\[ \text{AgCl(s)} \rightleftharpoons \text{Ag}^+\text{(aq)} + \text{Cl}^-\text{(aq)} \]

Which of the following statements is best supported by the particulate representation regarding the system at dynamic equilibrium?
