New cards
8

________ can give up more than one hydrogen in a solution.

Polyprotic acids

New cards
9

________ do not dissociate but accepts protons.

Bases

New cards
10

When just enough acid/base is added to an acid/base to neutralize

equivalence point

New cards
11

half-equivalence point

when exactly half the amount of acid/base is turned into its conjugate in a titration

New cards
12

Increasing ________ means decreasing [H+] and making a solution less acidic.

pH

New cards
13

________ means more acid dissociation (stronger acid)

Greater Ka value
