Separating Mixtures

Front

Mixture Noun

---

[miks-cher]

Back

Mixture

---

A physical combination of two or more substances where each retains its own chemical identity and properties.

---

Example: This diagram shows a solution, a type of mixture where solute particles are evenly distributed within a solvent, like salt dissolved in water.

Front

Solution Noun

---

[suh-loo-shun]

Back

Solution

---

A homogeneous mixture where one or more substances are uniformly dissolved in another substance, the solvent.

---

Example: This diagram shows a solution where solute particles (pink) are evenly mixed and dissolved within the solvent particles (blue) at a microscopic level.

Front

Dissolve Verb

---

[dih-zolv]

Back

Dissolve

---

The process where a solute incorporates into a solvent to form a solution by spreading out evenly.

---

Example: A solute (sugar) is added to a solvent (water), where it breaks down and spreads out evenly to form a solution (sweet water).

Front

Solute Noun

---

[sol-yoot]

Back

Solute

---

The substance in a solution that is dissolved by the solvent to form a homogeneous mixture.

---

Example: This diagram shows that a solute is the substance (yellow particles) that dissolves into another substance, the solvent (blue particles), to form a solution.

Front

Solvent Noun

---

[sol-vuhnt]

Back

Solvent

---

The substance in a solution that dissolves the solute, typically present in the largest amount.

---

Example: Water molecules, acting as the solvent, surround and pull apart the particles (ions) of a solid, causing it to dissolve into a solution.

Front

Homogeneous Mixture Noun

---

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

Back

Homogeneous Mixture

---

A mixture with a uniform composition and appearance throughout, where individual components are not visually distinguishable.

---

Example: This image shows that when a solute (salt) dissolves completely in a solvent (water), it forms a solution (salt-water), which is a homogeneous mixture.

Front

Evaporation Noun

---

[ih-vap-uh-rey-shun]

Back

Evaporation

---

A separation technique that removes a liquid solvent by heating, leaving the dissolved solid solute behind as residue.

---

Example: Heating a mixture of salt and water causes the water to turn into vapor (evaporate), leaving the solid salt behind in the dish.

Front

Filtration Noun

---

[fil-trey-shun]

Back

Filtration

---

A method for separating an insoluble solid from a liquid by passing the mixture through a porous filter.

---

Example: This diagram shows filtration, a process to separate an insoluble solid from a liquid using a filter that allows the liquid to pass through.

Front

Filtrate Noun

---

[fil-treyt]

Back

Filtrate

---

The clear liquid that has successfully passed through the filter paper during the process of filtration.

---

Example: This diagram shows filtration, where a liquid (orange juice) passes through a filter, leaving solids (pulp) behind. The clear liquid collected is the filtrate.

Front

Residue Noun

---

[rez-i-doo]

Back

Residue

---

The solid material that remains on the filter after filtration or is left behind after evaporation.

---

Example: This diagram shows filtration, where an insoluble solid is separated from a liquid. The solid particles trapped by the filter paper are called the residue.
