Chapter 10.2 Flashcards
1
Q
Is autoinozation a reversible process
A
-yes
2
Q
What happens to Kw as temperature also increases
A
-it will also increase
3
Q
What is a weak acid or base in relation to its Ka or Kb value
A
Ka
->for weak acid, it is less than one
Kb
->for weak base, it is less than one
4
Q
How are Ka and Kb related
A
- if Ka is large, then Kb is small
- > by this logic, a strong acid has a weak conjugate base
- if Kb is large, then Ka is small
- > by this logic, a strong base has a weak conjugate acid
-note for weak acids and bases, their conjugates are also weak
5
Q
How does induction affect acid strength
A
- electronegative elements positioned near an acid proton can increase acid strength
- > this is because it pulls the electron density of the bond holding the acidic proton
- > this weakens proton bonding and facilitates dissociation
6
Q
What kind of reaction is it when acids and bases react with each other. What is the reverse reaction referred to as.
A
- it is a neutralization reaction
- reverse reaction is a hydrolysis reaction
