Review for Quiz 2 Flashcards
Disacoiation
To see if something actually disolves in water
What is one thing to add when writing disacociation equations
No diatomics
Add charges
Should be (aq)
Ionic substances
Conduct electricity
Disacociate into ions
Molecular substances
Do not conduct electricity
Do not disacociate into ions
Alcohols
Do not conduct
Moecular with COOH
Acids
Molecules that ionize
Have acidic hydrogen (OH)
Or a H
Need to be separated
Conduct electricity
Important note with alcohols
There are no (s) since it is not ionic OH
What is solubility
Mass over volume
Saturated solution
Max amount of solute reached
Unsaturated solution
More solute can be added
Solubility equalibrium
Use double headed arrows when it says high solubility
The higher the temp
The higher the solubility
The higher the kinetic energy
The higher the disolving power
The hgiher the pressure for gasses
The higher the solubility
The higher the temperature for gases
The lower the solubility
Concetration
Mols per L
Also called M
Ion species concentration
Using required over given for concentrations
What is an important thing to find out concnetrations
Use sqaure brackets to indicate concentration
Net ionic equations
Balence the equation
Turn into ions
Cancel out specatator ions
Dilutions
The chemical amoutn does not change but the volume and concenteation does
What are sources of error if the experimental value is over the theoretical value
Filter paper not fully dry
Impurity of substance
What are sources of error if the experimental value is under the theoretical value
Purity of solutions
Use higher grade filter paper
Electroyles
All ionic compounds are
Conduct electriciyt
Element
Same atoms
