What are the six strong acids |
HCl, HBr, HI, HNO3, HClO4, H2SO4 |
|
Common ion effect |
The shift in an ionic equilibrium caused by the addition of a solute that takes part in the equilibrium |
|
Bronsted Lowry concept |
Acids donate protons, bases accept protons |
|
As temperature increases... |
The value of Kw increases |
|
Buffer |
A buffer solution is one that controls pH. A buffer is made by combining a weak acid with strong base or visa versa. |
|
Henderson hasselbach equation |
PH=pka+log(base/acid) |
|
Strong's acids have ___ dissociation |
100%, small pka |
|
Titration curves |
PH=pka midpoint is where acid is identifiable. For a weak acid at equivalence point pH is basic |
|
Weak acids have ___ dissocation |
Less than 100%, strong HA |
|
Solubility |
Mass/L |
|
Molar solubility |
Moles/L |
|
When Q>Ksp |
Solution will precipitate out |
|
What does K= |
((H3O)(A))/(HA) |
|
If [HB]/[B-]=.1 |
Pka=ph-1 |
|
If [HB]/[B-]=10 |
Pka=pH+1 |
