STOP!!!! This is all OLD material

Solutions:

A solution is a homogeneous mixture of two or more substances in which the molecules or atoms are completely dispersed. The constituents can be solids, liquids, or gases.

A solution is made up of two parts:

 

Solute: what is being dissolved

 

Solvent: what is doing the dissolving; usually larger quantity; water is the                       universal solvent

The amount of substance which can dissolve in a given solvent at a certain temperature.

Solubility=

Solubility Curve

You need to know how to read a solubility curve. The left side (y-axis) tells you how much solute can dissolve (in 100g of water) at a certain temperature (x-axis).

The lines/curves indicate the maximun amount of solute which can be dissolved in 100g of water at each temperature. We call this a saturated solution.

 

Any amount above the curve is said to be supersaturated; there is more solute than the solvent can hold, therefore the excess precipitates out/settles to the bottom.

 

Any amount below the line is called unsaturated, meaning more solute can be added. 

This graph shows the solubility in 100g of water so if you DO NOT have 100g of water then you need to set up a fraction and cross multiply!!

The golden rule of sulibility:      Like dissolves like

Polar substances can dissolve other polar subatances.

                All ionic compounds

                Water

                Covalent compounds with lone pairs OR different elements bonded to the                                                                                                              central atom

Nonpolar substances dissolve other nonpolar substances

                All -ane's, -ene's, or -yne's   (ex. benzene, methane...)

                Oils

                Covalent compounds with no lone paris AND all elements bonded to the                                                                                           central atom are the same

Acids and Bases:

You need to memorize and understand these consepts.

Measured by:

Bronsted-Lowry Definition

Arrhenious definition

You need to understand the pH and pOH scale and make calculations based off of pH,pOH, [H+], and [OH-].
