Finding pH Flashcards
1
Q
Kb/Ka=
A
10^-pk
2
Q
pH=
A
-log([H+]/[OH-])
3
Q
What does strong base indicate?
A
The base will FULLY dissociate
-> [base]=[OH-]
4
Q
pH to find the concentration?
A
10^-xpH
5
Q
What happen when the concentration of base is very Low?
A
•the contribution of base conc due to auto-ionisation of water is no longer negligible
•[OH-] acid = [OH-] NaOH + [OH-] H2O
= x
=> pOH= -log(x)
