Homogeneous Mixtures

Particles that are evenly distributed or blended || Also called solutions

Heterogenious Mixtures

Do not blend smoothly throughout and the individual substances remain distinct.

Suspension

Type of heterogenious mixture whose particles settle out over time and can be separated from the mixture by filteration.

solute

Substance that dissolves in a liquid

Solvent

Dissolving Medium

Soluble

Describes a substance that can be dissolved in a given solvent

Micible

Two liquids that can be easily mixed with each other.

Insoluble

Descries a substance that cannot be disolved in a given solvent

Immisible

Describes two liquids that can be mixed together but separates shortly afterwards.

Concentration

Measures how much of a substance (solute) is dissolved in a specific amount of solvent or toatl solution.

Concentrated

Has a lot of solute

Dilute

Has only a little soluteM

olarity

How much solute is in one Liter of solution

Three steps to prepare molar solutions

1. Specified solute is added to a volumetric flask that has some water

2. Dissolve the solute

3. Fill to the last volume

Solvation

Another word for dissolving solvent particles

They wrap around the solute

Solubility

The limit of how much can dissolve

How to make a solid solution dissolve faster

1. Stir rapidly

2. INcrease the temperature

3. crush to increase surface area

Saturated solution

A mixture that has dissolved the maximum amount of solute possible in a solvent at given temperature

Unsaturated solution

Less than the maximum amount of solute

Supersaturated SOlution

Holds more than the max amount of solute

Colligative properties

Changes in a solution that depend only on how many particles are dissolved. St

strong electrolyte

A substance (solute) that dissolves in water and completely breaks apart (disassociates) into ions

Weak Electrolyte

Forms some ions

Nonelectrolyte

Forms No ions

Reversible reaction

A chemical reaction that can occur both in the forward and the reverse direction
