If the solubility of a solid changes very little with temperature, what will its solubility curve look like?
Answer and explanation
Correct answer: Nearly horizontal
The slope of a solubility curve represents how strongly solubility changes with temperature. If the solubility changes only slightly over the temperature range, the slope is small and the graph appears nearly horizontal. A steep upward curve would show a large increase, while a vertical curve would indicate an unrealistically rapid change. Curve shape must be inferred from the stated dependence.
