Heterogenous mixtures

A combination of two or more pure substances in which each retains its individual properties

Ex. of a Heterogenous Mixture

Orange Juice: The juice and the pulp are not blended perfectly

What are two types of heterogenous mixtures?

Colloids and Suspensions

Suspension

A mixture containing particles that settle out if left undisturbed.

Example of a Suspension

Muddy water/lakes: Mud and rocks settle at the bottom and water is clear

Colloid

A heterogenous mixture of intermediate-sized particles (between 1nm and 100nm in diameter) that are made of dispersed mediums and dispersion mediums (Basically mixtures that can’t be filtered out into separate solutions)

Dispersion Medium

The most substance in a colloid mixture

Tyndall effect

A phenomenon in which dispersed colloid particles scattered lights

Colloids make what kind of movement?

Jerky random movements called Brownian motion. Results from collision’s of particles of the dispersion medium with the dispersed particles

Homogenous mixtures

Also known as solutions; contain two or more substances called the solute and the solvent

Solute

Substances that dissolve

Solvent

The dissolving medium

The Universal Solvent

Water

Solution

A uniform mixture that contains solids, liquids, and gasses; also known as a homogenous mixture

What does soluble mean?

Describes a substance that can be dissolved in a give solvent

Example of soluble

Sugar is soluble in water

What does insoluble mean?

A substance that does not dissolve in solvents

Example of insoluble

Sand cannot dissolve in water

Miscible

Two liquids can be soluble in each other

Example of miscible liquids

Milk and water; Alcohol and Water

Immiscible

Two substances that can be mixed together but separates shortly after

Ex of Immiscible

Oil and Water

Concentration

The measure of how much solute is dissolved in a specific amount of solvent and solution

When something is concentrated it is?

A solution with a large amount of solute in comparison to solvent

When something is diluted it is?

A solution with a large amount of solvent in comparison to solute
