AQUEOUS IONIC EQUILIBRIUM Flashcards
1
Q
pH formula
A
pH = pka + log[base]/[acid]
2
Q
pOH formula
A
pOH = pkb + log[acid]/[base]
3
Q
pka formula
A
pka = pH - log[acid]/[base]
4
Q
pkb formula
A
pkb = pOH -log[acid]/[base]
5
Q
Calculating change in buffer solution rules ACID
A
If adding acid, subtract whatever you added on top, and add whatever you added on bottom.
6
Q
Calculating change in buffer solution rules BASE
A
If adding base, add whatever you added on top, and subtract whatever you added on bottom
7
Q
Equivalence point
A
Where acid/base completely neutralize (neither is in excess)
8
Q
1/2 equivalence point
A
Where half the acid/base reacts with titrant
