Integrated Science: Mixtures, Separation Techniques, and Properties

Comprehensive vocabulary flashcards covering mixture types (solutions, colloids, and suspensions), property comparisons, and separation techniques for Integrated Science.

Solution

A mixture with a particle size of less than $1\,\text{nm}$, a clean appearance, that does not separate, passes through filter paper, and allows light to pass through, exemplified by salt solution.

Colloid

A mixture with a particle size of $1\,\text{nm}$ to $100\,\text{nm}$, a cloudy appearance, that does not separate, passes through filter paper, and scatters a beam of light, exemplified by mayonnaise.

Suspension

A mixture with a particle size of more than $100\,\text{nm}$, a cloudy appearance, that separates or settles, does not pass through filter paper, and does not allow light to pass through, exemplified by muddy water.

Solution Particle Size

Less than $1\,\text{nm}$.

Colloid Particle Size

$1\,\text{nm}$ to $100\,\text{nm}$.

Suspension Particle Size

More than $100\,\text{nm}$.

Filterability

The property describing whether particles can pass through filter paper; solutions and colloids pass through, whereas suspensions do not.

Effect of Beam of Light on a Colloid

Scatters light.

Effect of Beam of Light on a Suspension

Light cannot pass through.

Effect of Beam of Light on a Solution

Light can pass through.

Mayonnaise

A specific example of a colloid with a cloudy appearance that scatters light and has particle sizes between $1\,\text{nm}$ and $100\,\text{nm}$.

Muddy Water

A specific example of a suspension that has a cloudy appearance, separates or settles, and blocks light.

Salt Solution

A specific example of a solution that has a clean appearance, does not separate, and lets light pass through.

Magnetic Separation

A separation technique identified as one of the structured question topics in Section B alongside filtration, evaporation, or chromatography.

Filtration

A separation technique based on the ability of mixture components to pass through filter paper.

Evaporation

A separation technique included as a core topic for the Section B structured questions.

Chromatography

A separation technique listed among the assessment topics for structured questions in Section B.

Solute

The component of a solution that is dissolved, tested in conjunction with solvents and separation techniques.

Solvent

The liquid or dissolving substance that dissolves a solute, included as a key assessment topic for multiple choice and structured questions.
