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

33

alcohols and acidity

not acidic at all
