Hi, am just a bit unsure about this area of the topic:
When a weak acid dissociates into a proton and anion ...
HA <==> H+ + A-
Does the concentration of hydrogen ions (H+) always equal the concentration of the anion (A-) here?
Also I have found the formula
Total concentration = Concentration of ionised + concentration of undissociated.
To use this formula would I take the "concentration of ionised" to be just
[A-] or would it be [A-] + [H+]? I was thinking it would be just [A-]. Though am unsure of the explaination.
Clearly for "concentration of undissociated" this would be [HA] value.
Any help with this confusion would be greatly appreciated!
Many Thanks!
