Acids And Bases Flashcards
1
Q
pKa
A
-log10Ka
2
Q
Ka
A
The acid dissociation constant it tells us how weak/strong a weak acid actually is
3
Q
Buffered solutions
A
Contains material that minimises change in pH when a relatively small amount of a strong acid/base is added
4
Q
Acetic acid buffer example equation
A
CH3COOH + H2O CH3COO- + H3O+
5
Q
Why must weak acids and bases be calculated by Ka
A
Because [H30+] is not equal to [added acid]
