16
Q

How do you find pKa from Ka?

A
  • log which cancels out the base 10 so pKa is the positive exponent of Ka
17
Q

If you have a strong acid what is the conjugate base strength?

18
Q

If you have a strong Base what is the conjugate acid strength?

19
Q

What side does equilibrium favor

A

the weaker acid and base

20
Q

Element in same row which will be more acidic

A

acidity increases across periodic table as electronegativity increases

21
Q

What how is acidity affected going down column of periodic table

A

As you go down the periodic table acidity increases because the size of the atom increases

22
Q

inductive effect

A

electron deficent carbon pulls electron density through sigma bonds from negatively charged atoms

23
Q

How does inductive effect effect acidity

A

More electronegative atoms more than C means more acidity as well that it is closers to each other

24
Q

How does resonance effect acidity?

A

delocalization increases acidity due to base being stablilized

25
Q

how does hybridization effect acidity

A

more bond increases acidity

26
Q

What factors determine acidity

A

Element, inductive, resonance, hybridization

27
Q

What are common acids

A

HCL, H2SO3, acetic acid, ptoluenesulfonic acid

28
Q

What are common bases

A

-OH, -NH2, H-

29
Q

lewis acid-base reaction

A

lewis base donates an electron pair to lewis acid

30
Q

What is a lewis acid and what does that mean

A

electrophile= electron loving

31
Q

What is an lewis base and what does that mean

A

nucleophile= nucleus loving
