|
Electrolytes |
Dissolve in water to give ions |
|
|
Solubility rules |
Predict the extent to which an ionic compound will dissolve in water |
|
|
Molecular equation |
Substances are written as if they were molecular even though they are ionic. It does not describe what's happening at the level of ions and molecules |
|
|
Complete ionic equation |
Replaces molecular equation with strong electrolytes' ionic formula |
|
|
Net ionic equation |
Complete ionic equation without spectator ions |
|
|
Three types of reactions |
Precipitation reactions Acid – base reactions Oxidation – reduction reactions |
|
|
Precipitation reaction |
Occurs in aqueous solution because one product is insoluble. You can decide whether two ionic compounds will result in a precipitation reaction if you know the solubility rules that one of potential products is insoluble |
|
|
Acids |
Yield hydrogen ions or donate protons |
|
|
Bases |
Yield hydroxide ions or accept protons |
|
|
Acid-base reactions |
Proton transfer reactions |
|
|
Oxidation-reduction reactions |
Involve a transfer of electrons from one species to another or change in the oxidation number of atoms Oxidation and reduction must occur in the same reaction |
|
|
Oxidation numbers |
And increase results in oxidation, a decrease results in reduction |
|
|
Oxidation – reduction reaction categories |
Combination reactions, decomposition reactions, displacement reactions, and combustion reactions |
|
|
Half reaction method |
The balancing of oxidation – reduction reactions |
|
|
Molar concentration/molarity |
The moles of solute in a liter of solution
Allows you to calculate the amount of solute in any volume of solution |
|
|
Dilution of a solution |
Moles of solute remain constant, allowing the dilution with a desired volume to achieve a desired molarity |
|
|
Quantitative analysis |
Determination of the amount of a species any material |
|
|
Gravimetric analysis |
Determines the amount of a species by converting it to a product you can weigh |
|
|
Volumetric analysis |
Determines the amount of species by titration |
|
|
Titration |
Method of chemical analysis allows the measure of the volume of a solution of a known molarity that reacts with a compound of an unknown amount. this determines the amount of compound in this volume of solution |
