Polyprotic acids
________ can give up more than one hydrogen in a solution.
9
New cards
Bases
________ do not dissociate but accepts protons.
10
New cards
equivalence point
When just enough acid/base is added to an acid/base to neutralize
11
New cards
half-equivalence point
when exactly half the amount of acid/base is turned into its conjugate in a titration
12
New cards
pH
Increasing ________ means decreasing [H+] and making a solution less acidic.
13
New cards
Greater Ka value
________ means more acid dissociation (stronger acid)
14
New cards
Greater Kb value
________ means more protonatization (stronger base)
