ACIDS AND BASES Flashcards
1
Q
Conjugate acid
A
Add H+
2
Q
Conjugate base
A
Remove H+
3
Q
Finding pH/pOH
A
pH = -log(H3O)
pOH = -log(OH)
pH + pOH = 14
4
Q
Finding [H3O]/[OH]
A
[H3O] = 10^-pH
[OH] = 10^-pOH
5
Q
Finding pKa/pKb
A
pKa = -log(Ka)
pKb = -log(Kb)
pKa + pKb = 14
6
Q
Finding Ka/Kb
A
Ka = 10^-pka
Kb = 10^-pKb
7
Q
Finding Ka/Kb in Kw reaction
A
Ka = Kw/Kb?
Kb = Kw/Ka
8
Q
Strong acids
A
Ionice completely 100% and single arrow
9
Q
Weak acids
A
Ionize less than 5% and double arrow
10
Q
Acid theories
A
- Arrhenius acids release H+ in soln
- Bronsted Lowry acids are H+ donors
- Lewis acids are electron pair acceptors
11
Q
Base theories
A
- Arrhenius base release OH- ion
- Bronsted Lowry bases are H+ acceptors
- Lewis acids are electron pair donors
12
Q
Do we include H2O in acid base reactions on ICE
A
no ignore
13
Q
Polyprotics
A
Acids with more than one ionizable proton (use first Ka1 value)
14
Q
H2SO4 specific rules
A
If [H2SO4] is >1.00 we only consider first ionization . When [H2SO4] is <0.01 use both ionization
15
Q
Review acid base properties
A
