Problem
Two 1.00 g liquid samples are withdrawn from opposite sides of an undisturbed beaker. Each sample contains exactly 0.20 g of dissolved NaCl. Which statement about the mixture in the beaker is most accurate?
(a) The mixture is supersaturated with respect to NaCl and will precipitate if disturbed.
(b) The mixture is homogeneous throughout the beaker.
(c) The beaker actually contains two liquid layers, a denser salt solution beneath a less-concentrated layer.
(d) The mixture is saturated; it already contains the maximum amount of NaCl that can dissolve at this temperature.
