Q
Bronsted Lowry base
A
Proton acceptor
3
Q
Acid
A
HA + H2O = H30+ + A-
4
Q
Base
A
B + H20 = BH+ +OH-
5
Q
ionic product of water
A
Kw= h+ oh-
6
Q
pure water
A
kw= (h+)2
7
Q
ph scale
A
the concentration of hydrogen ions on logarithmic scale
8
Q
ph
A
-log10(h+)
9
Q
h+
A
10-ph
10
Q
ka for weak acid
A
h2 / ha
h *a /ha
11
Q
pka
A
-log10ka
12
Q
ka
A
10-pka
13
Q
buffer actions
A
a buffer resists changes in PH
14
Q
acidic buffers made from weak acid and salts
A
add h+ / acid the concentration increases and shifts to left as it combines with the ethanoate to form the acid. moving to left reduces h+ conc
15
Q
adding OH-
A
react with h to from water fromving h+. more acid to dissociate and shifts equilibrium to right
