1
Arrhenius theory
acid donates protons, OH
2
bronstead lowry
acid is proton donor, base is proton acceptor
3
acid to conjugate base
take away H
4
base to conjugate acid
Add H
5
aphiprotic/amphoteric
can donate and accept protons
Ie water
6
review learning checks
ok
7
Kw
1.0 X 10^ -14
8
when asked for ion concentrations
give all ions but ALSO OH and H+
9
pH and sig digs
number of decimal places in pH value is the number of sig figs
10
pH + pOH
14.00
11
remember to put the right arrows for strong acids and bases
yes
12
major species in strong acids and bases
ions and water
13
major species in weak acid and base
water and weak acid/base
14
oxyanions to acid
"ate ic" "ite ous"
15
carboxylic acid
CO2H
- always weak acids
16
which H will become acid
the one attached to O
17
COH ionizes
never!
18
most common weak bases
have nitrogen with 3 bonds and lone pair
19
strong acid and base in water
neutral
20
weak acid conjugate base in water
is basic
21
cations of weak bases
acidic
22
NH4+ in water
acidic
23
weak bases
anything not group 1 or Ca, Sr, Ba
24
KaKb
= kw
25
pKa + pKb
14.00
26
higher ka
more likely to loose H
27
polyprotic acid and strength
first H is strong, then gets weaker
28
more electronegative atoms and H loss
means less electrons around H bond, easier to break
29
atomic radius and H loss
larger orbitals, less overlap, weaker bonds, higher acidity
30
oxyacids and H loss
more EN atom will take electrons so more acidic
31
hypohalous
HO and halogen
32
carboxylic acids and acidity
take away electrons from whole atom so more acidic, less electron cloud
also, can have resonance so more stable
