Problem
A magnified particulate-level diagram depicts randomly moving red spheres (A+) and blue squares (B−) in solution. After mixing, many of the ions arrange into large, ordered clusters that settle toward the bottom, while some free ions remain dispersed in the liquid. Which macroscopic observation is most consistent with this diagram?
(a) The solution becomes cloudy, but no solid collects at the bottom of the beaker.
(b) The solution turns a darker color while remaining completely clear.
(c) A solid precipitate forms and settles to the bottom of the beaker.
(d) The temperature of the solution increases noticeably, yet the liquid stays transparent.
