Chapter 13, Problem 13.41QP
The diagrams represent an aqueous solution at two different temperatures. In both diagrams, the solution is saturated in two different solutes, each of which is represented by a different color. Using the diagrams, determine for each solute whether the dissolution process is endothermic or exothermic. For which of the solutes do you think the numerical value of ΔHsoln is greater? Explain.
