chem final practice, almost everything

everything besides conversion factors and homo/hetero mixutres

kw equation

[OH-][H30+] = 1e-14

pH equation

pH = -log[H30+]

pOH equation

pOH = -log[OH-]

[H30+] equation

[H30+] = 10^-pH

[OH-] equation

[OH-] = 10^-pOH

Oxidation is (goes with RA)

OIL - LOSS of e-, charge goes up (more pos).

Reduction is (goes with OA)

RIG - GAIN of e-, charge goes down (more neg).

OA

Thing being reduced

RA

thing being oxidized

Oxidation state is fancy for

charge

neutralization is fancy for

DR

[ ] mean what?

Molarity

soluable means

AQ, does dissolve

Insoluable means

s, no dissolve.

PP - 5 senses

can be measured/seen w/o changing composition/identity of a substance. 5 senses. "absorb, freeze, melt, boil, dissolve"

PC - can “fix it”

Composition remains the same. Ex: breaking glass, tear pape

CC - after

Composition converts into a "new one".

CP - could/potential

Only be measured by changing the composition/identity of a substance. "Can, Does/n't, Has/n't the ability to"
