A solution that resists changes in pH when a small amount of strong acid or strong base is added
The pH is equal to the _________ when the concentration of an acid and its conjugate base are equal.
The dissociation of HA is minimal.
What assumption is made in problems involving weak acid dissociation?
To prepare a buffer, combine equal ___________ of equal _____________ of an acid and its salt.
To prepare a buffer, combine a certain number of moles of a weak acid with ___________ the number of moles of a strong base.
In titrations, the name given to the point at which an equal number of moles of acid/base have been combined
Part of a titration curve where the solution maintains the most constant pH (pKa = pH, the amount of base equal to half the amount required to reach equivalence has been added).
An indicator should be chosen with a pKa as close to the pH of the _____________ as possible (within one pH unit).
Acids react with metals above hydrogen in the reactivity series to produce __________ and a ___________.
An acid is ____________ if it dissociates to give 2 mol of hydrogen ions in solution (for a strong one of these, [H+] will be twice the concentration of the acid).
