A
Ka
2
Q
When OH- is added to a solution…
A
It will be consumed by the acid in a acid/base buffer
3
Q
pH of a strong acid/strong base titration
A
pH = 7
4
Q
pH of a strong base/weak acid titration
A
pH > 7
5
Q
pH of a strong acid/weak base titration
A
pH < 7
6
Q
Exhibit the lowest pH
A
Most acidic
Highest oxidation number
7
Q
H2A
A
Binary acid
Stronger down a group because of increased size
Stronger across a period because of increased electronegativity
8
Q
H2AO3
A
Oxyacid
Higher oxidation state means more polar bond
More electronegative means more acidic
9
Q
Lewis acid
A
Electrophile willing to “accept” a lone pair of electrons from a Lewis base
