Which term refers to a graph indicating the solubility of a solute at different temperatures?

• A. Solubility Plot
• B. Dissolution Graph
• C. Boiling Point Curve
• D. Solubility Curve

Answer: (D)

The main idea here is understanding how a graph shows how much solute can dissolve at different temperatures. The standard term for this is a solubility curve. It plots solubility on the vertical axis against temperature on the horizontal axis, illustrating the maximum amount of solute that can dissolve at each temperature before the solution becomes saturated. This helps you predict how much solute will dissolve as the temperature changes, which is why the curve is the right name—the graph forms a characteristic curve of solubility. Other terms aren’t as appropriate: a solubility plot isn’t the common label, a dissolution graph normally refers to the rate of dissolving over time, and a boiling point curve deals with boiling temperatures rather than solubility.
