9
New cards

________ do not dissociate but accepts protons.

Bases

10
New cards

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

equivalence point

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

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

pH

13
New cards

________ means more acid dissociation (stronger acid)

Greater Ka value
