Solubility Curves

Front

Solution Noun

---

[suh-loo-shun]

Back

Solution

---

A homogenous mixture where two or more substances are evenly mixed and distributed at a molecular level.

---

Example: This diagram shows a solution in a beaker, clearly labeling the solute (the substance being dissolved) and the solvent (the substance doing the dissolving).

Front

Solute Noun

---

[sol-yoot]

Back

Solute

---

The substance in a solution that is being dissolved by another substance, typically present in a smaller amount.

---

Example: The image shows a solute, like a salt crystal, breaking apart into individual ions as it dissolves in a solvent, like water.

Front

Solvent Noun

---

[sol-vuhnt]

Back

Solvent

---

The substance in a solution that does the dissolving of another substance, typically present in the largest amount.

---

Example: This image shows how a solvent, like water, surrounds and pulls apart solute particles, like salt ions (Na+ and Cl-), causing them to dissolve.

Front

Solubility Noun

---

[sol-yuh-bil-i-tee]

Back

Solubility

---

The maximum amount of a solute that can be dissolved in a given amount of solvent at a specific temperature.

---

Example: This graph, a solubility curve, shows how much of a substance (like sucrose) can dissolve in water as the temperature increases.

Front

Solubility Curve Noun

---

[sol-yuh-bil-i-tee kurv]

Back

Solubility Curve

---

A graph that plots the solubility of a substance against temperature, used as a reference tool for analysis.

---

Example: This graph, a solubility curve, shows how much of a substance can dissolve in a liquid at different temperatures, indicating saturated, unsaturated, and supersaturated solutions.
