Q
strong acid vs weak acid
A
strong acid - ALL H+ dissociation
weak acid - partial H+ dissociation
8
Q
Strong base vs weak base
A
Strong base - takes ALL H+ ions
weak base - partial H+ ion taking
9

Strong Base
27
weak acids are ________ in net ionic equations
not dissociated
28
pH
- log [H+]
29
pOH
- log [OH-]
30
pH and pOH relationship
at 25 Celsius
pH + pOH = 14
31
Henderson-Hasselbach Equation
pH = pKa + log ([Base]/[Acid])
32
What determines the strength of the acids and bases?
structure of molecule
33
Left to Right Acid strength
increase
MORE ELECTONEGATIVITY 👹👹👹👹
34
Down acid strength
increase
LONGER DISTTTTANNNCEEE bond
columbs law
35
More electronegative an atom is... acid strength is
increase
36
Addition of COOH or carboxyl acid strength
increase
37
Weak Acid is....
Strong Base
38
The more stable the conjugate base...
the stronger the acid
39
More electronegative atoms - O F Cl I
stronger acid
40
What do you use in Weak Acid Base Problems
ICE tables
41
Ka and Kb relatinship
KaKb = Kw
42
Strong Acid and Strong Base
H+ + OH- = H2O
ALL OTHERS = SPECTATORS
43
MaVa = MbVb
REPEATTTTTTTTT
44
Strong Acid Strong Base, equi =
pH = 7
45
Weak Base Strong Acid, equi =
pH < 7
46
Strong Base Weak Acid, equi =
pH > 7
47
Key point on indicators
pKa = pH of equi
48
Buffer
Mixture of weak acid and conjugate base or vice versa
49
The lower the concentration of buffer, the lower the
buffer capacity
