|
common ion effect
|
The shift in equilibrium position that occurs because of the addition of an ion already involved in the equilibrium reaction
|
|
|
buffered solution
|
a solution that resists a change in its pH when either hydroxide ions or protons are added
|
|
|
Henderson-Hasselbalch equation
|
the log form of the acid dissociation equilibrium expression, useful for calculating the pH of solutions when the ration of acid to conjugate base is known
|
|
|
buffering capacity
|
the amount of protons or hydroxide ions the buffer can absorb without a significant change in pH
|
|
|
pH curve (titration curve)
|
the plot of the pH of a solution as a function of the amount of titrant added
|
|
|
equivalence point (stoichiometric point)
|
the point at which enough titrant has been added to react exactly with what is being titrated
|
|
|
acid-base indicator
|
marks the endpoint of a titration by changing color
|
|
|
phenolphthalein
|
a commonly used acid-base indicator
|
|
|
end point
|
point at which the indicator changes color
|
|
|
effloresce
|
to change either throughout or on the surface to a mealy or powdery substance upon exposure to air, as a crystalline substance through loss of water of crystallization.
|
|
|
effervesce
|
to give off bubbles of gas
|
|
|
hygroscopy
|
the ability of a substance to attract and hold water molecules from the surrounding environment
|
|
|
hydrophobe
|
physical property of a molecule that is repelled from water
|
|

hydrophile
|
physical property of a molecule that is attracted to water
