Homogeneous and Heterogeneous Mixtures

Front

Mixture Noun

---

[miks-cher]

Back

Mixture

---

A substance made by combining two or more materials that are not chemically bonded and retain their individual properties.

---

Example: This diagram shows salt and water, two separate substances, being combined and stirred to form a solution, a type of homogeneous mixture.

Front

Compound Noun

---

[kom-pound]

Back

Compound

---

A substance formed when two or more chemical elements are chemically bonded together in fixed proportions by mass.

---

Example: This diagram shows a molecule of the compound carbon dioxide (CO₂), where one carbon atom is chemically bonded to two oxygen atoms.

Homogeneous Mixture Noun

---

[hoh-moh-jee-nee-uhs miks-cher]

Back

Homogeneous Mixture

---

A mixture in which the components are uniformly distributed, resulting in the same composition and properties throughout the substance.

---

Example: This diagram shows a solution, a type of homogeneous mixture, where solute particles are evenly distributed throughout the solvent, creating a uniform composition.

Front

Heterogeneous Mixture Noun

---

[het-er-oh-jee-nee-uhs miks-cher]

Back

Heterogeneous Mixture

---

A mixture in which the components are not uniformly distributed, and different samples can have different properties.

---

Example: This image shows that in heterogeneous mixtures like tacos, pizza, or a salad, you can easily see the different, separate parts that make them up.

Front

Solution Noun

---

[suh-loo-shun]

Back

Solution

---

A type of homogeneous mixture where one substance's particles are dissolved in another, being too small to see or separate.

---

Example: This diagram shows a solution where solute particles (pink) are completely dissolved and evenly mixed with solvent particles (blue), creating a uniform homogeneous mixture.

Front

Suspension Noun

---

[suh-spen-shun]

Back

Suspension

---

A heterogeneous mixture containing solid particles large enough for sedimentation, which will eventually settle out if left undisturbed.

---

Example: This diagram shows that a suspension is a heterogeneous mixture, like sand in water, where solid particles are temporarily mixed but will eventually settle to the bottom.

Front

Colloid Noun

---

[kol-oid]

Back

Colloid

---

A mixture where one substance of microscopically dispersed insoluble particles is suspended throughout another substance without settling out.

---

Example: This diagram shows that a colloid is a mixture formed by combining a smaller amount of a 'dispersed phase' with a larger amount of a 'dispersion medium'.

Front

Homogenization Noun

---

[hoh-moj-uh-nuh-zey-shun]

Back

Homogenization

---

The process of reducing the size of particles in a fluid to make them uniformly small and evenly distributed.

---

Example: This diagram shows milk before and after homogenization. The process breaks large fat globules into smaller particles, distributing them evenly to create a stable, homogeneous mixture.
