Analyzing a Solubility Curve

These flashcards cover key terms and concepts related to the solubility curve, including definitions of various types of solutions, specific examples of solute behavior, and questions regarding their properties.

Solubility Curve

A graphical representation of the relationship between the solubility of a solute and the temperature.

Saturated Solution

A solution in which the maximum amount of solute has been dissolved at a given temperature.

Supersaturated Solution

A solution that contains more solute than the solvent can normally hold at a given temperature.

Unsaturated Solution

A solution that contains less solute than the maximum amount that can be dissolved at a given temperature.

KClO3 at 50°C

20 grams of KClO3 can be dissolved in 100 grams of water.

Most Soluble Substance at 10°C

KI is the most soluble substance in 100 grams of water at 10°C.

Least Soluble Substance at 10°C

KClO3 is the least soluble substance in 100 grams of water at 10°C.

Effect of Temperature Increase on KNO3

KNO3 is most affected by an increase in temperature, showing the greatest change.

Substances Less Soluble as Temperature Increases

HCl, NH3, and SO2 become less soluble in water as the temperature increases.

Supersaturated Solution Example

A solution with 40 grams of NaCl in 100 grams of water at 90°C, which becomes supersaturated when cooled to 40°C.
