Finding pH

Question 1

Kb/Ka=

Answer 1

10^-pk

Question 2

pH=

Answer 2

-log([H+]/[OH-])

Question 3

What does strong base indicate?

Answer 3

The base will FULLY dissociate

-> [base]=[OH-]

Question 4

pH to find the concentration?

Answer 4

10^-xpH

Question 5

What happen when the concentration of base is very Low?

Answer 5

•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)
