What are aqueous solutions |
Solutions in which water is the solvent |
|
|
Ionic compounds |
Metal and a non-metal Separate into ions Includes acids and ammonium salts |
|
|
Molecular compounds |
Non metals only Do not conduct electricity Include all organic compounds |
|
|
What is solubility |
Concentration of a substance in a saturated solution |
|
|
Saturated solutions |
Solid solute in equilibrium with dissolves solute Some solid must be present Rate of dissolving=rate of crystallization |
|
|
Low solubility |
If it dissolves very minimally (less than 0.1M) Precipitate forms |
|
|
Formula equations |
Regular, balanced, double-replacement equations |
|
|
Complete ionic equations |
Show all ions but precipitates are written as compounds Must be balanced |
|
|
Net ionic equations |
Show only ions that react and the precipitate that forms No spectator ions |
|
|
Why to use to remove calcium and magnesium from hard water |
Na2CO3 baking soda |
|
|
What is hard water |
Has too many ions due to limestone erosion Bitter, leaves deposits, soap won’t lather |
|
|
Large vs small Ksp value |
Large ksp : more soluble salt Small ksp : less soluble |
|
|
Did a ppt form based on Q? |
If Q If Q=ksp minima ppt forms If Q If Q>ksp excess of ions, ppt forms |
|
|
What happens when 2 ions form a compound having low solubility |
A precipitate forms |
