Solutions Notes

Solutions Definition

Solutions are the most perfect mixtures; they break down to individual atoms but do NOT bond with the water.

Solid solution is alloy (stainless steel, bronze)

Liquid Solution is lemonade (water, sugar, flavor) or soda (water, flavoring, CO

2

)

Gas Solution is air (Oxygen, Nitrogen, Carbon dioxide)

Components Solutions have two components (Demo)

Solvent

Solute

Strength or

Degrees of

Concentration

Solvent - the fluid that "dissolves" and "holds up" the substance being dissolved.

Water is known as the universal solvent - Aqueous solution. It dissolves more things than anything else.

Acids and bases are only acids and bases when dissolved in water. - Gasoline is a solvent but it won't create an acid or base

Solute - the thing being dissolved. (the substance with the smaller amount.)

Solutes can be solid, liquids, or gases - Sugar, Lemon Juice(lemonade), CO

Pop)

(Soda

Solutions have differing strengths

Dilute - Not a lot of solute dissolved in the solvent

Concentrated - Lots of solute dissolved in the solvent

A saturated solution - A solution in which the maximum amount of solute has been dissolved.(ultra-concentrated)

Saturation point is affected by temperature.

Suspension

Characteristic

Properties

Does not break down into individual molecules.

Eventually will settle out.

Adding solutes increases the boiling point and lowers freezing point of most solutions

Anti-freeze in radiators, vodka in freezer.
