Unit 10SOLUTION CHEMISTRY!

What is a solution?A solution is an answer to a problem.ORA solution is a homogenous mixture of 2 or

more substances.

Solutions have two parts to them…Solute: the substance that is being dissolved.

Ex: SALT (NaCl), Chocolate!Solvent: the substance that is doing the

dissolvingEx:WATER , Milk

WATERWater is known as the Universal Solvent

It is known as this because of polarityThe hydrogens have a partially positive chargeThe oxygen has a partially negative charge

More WaterWhen water acts as the solvent the process is

called hydration.When you are deHYDRATED that means you

haven’t had enough WATER

Solvation If another substance acts as the solvent the

process is called solvation, which means the solvent surrounds the solute and pulls it apart making it dissolve.

Concentration and SolubilityA solution can be measured by its

concentration. There are three basic measurements of solubility.

Saturated SolutionsSaturated means the solution contains the

maximum amount of solute that can be dissolved in a solution.

Supersaturated SolutionsSupersaturated means the solution contains

more than the maximum amount of solute that can be dissolved in the solution.

Unsaturated SolutionsAn unsaturated solution means it contains

very little solute.

Saturated

SUPER saturated

UN

Saturated

To dissolve or not to dissolve….Not all solutes are able to dissolve in solvents

If a solute DOES NOT dissolve is a solvent it is called immiscible

If a solute DOES dissolve in a solvent it is called miscible
