Chapter 8 - Acids and Bases Flashcards
1
Q
Arrhenius acid
A
Yields H3O+ when added to H2O (aq: [H3O+]>[OH-])
2
Q
Arrhenius base
A
Yields OH- when added to H2O (aq: [OH-]>[H3O+])
3
Q
Bronsted-Lowry acid
A
Proton donor (HX in protic solvent)
4
Q
Bronsted-Lowry base
A
Proton acceptor (KOH in protic solvent)
5
Q
Lewis acid
A
Electron pair acceptor (BF3 in aprotic solvent)
6
Q
Lewis base
A
Electron pair donor (NH3 in aprotic solvent)
7
Q
What does it mean that water is amphoteric?
A
It may act as either an acid or a base
8
Q
What is considered a neutral aqueous solution?
A
One in which [H3O+]=[OH-] and therefore, pH=pOH
9
Q
What is considered a basic aqueous solution?
A
[OH-]>[H3O+], so pH > pOH
10
Q
What type of solution will turn blue litmus paper red?
A
any acidic solution with a pH of less than 7.0
