3

List of Intermediate Products

H2CO3
H2SO3
NH4OH

4

Intermediate products are also known as

Gas Evolution

5

Oxidation is ____, Reduction is _____

Loss, Gain

6

O.I.L R.I.G

Oxidation is loss, Reduction is gain

7

Limiting reactant is the _____ outcome

Smallest

8

Percent Yield Equation

Actual / expected x 100

9

How do you find the expected in percentage yield?

use limiting reactant

10

What do you use when asked for what is left after the reaction?

Start - used = left
- Start is given
- Used is found using limiting reacted
- Left is answer

11

What is the equation for moles?

n = C * V

12

Endothermic

heat goes INTO the reaction
ΔH > 0

13

Extothermic

Heat EXITS reaction
ΔH < 0

14

From a base to a conjugate acid what happens to H+

conjugate acid gains an H+

15

From an acid to conjugate base what happens to H+

conjugate base loses an H+

16

What happens to a strong acid/base when placed in H2O

Fully dissociates/ionizes

17

What happens to a weak acid/base when placed in H2O

Does NOT dissociates/ionizes
- prefers to remain intact

18

If you add acid to H2O

[H3O+] goes up
[OH-] goes down

19

if you add bases to H2O

[H3O+] goes down
[OH-] goes up

20

Finish the equation:
[H3O+] [OH-] =

1.0E-14
or
1.0 x10^ -14

21

pH equals ...
pOH equals ...

pH 8.6
pOH 5.4
