Lecture 11 Flashcards
1
Q
What are salts
A
Ionic compounds (adding salt doesn’t make acidic)
2
Q
When does a salt affect pH
A
If their anions/cations recombine with H+
3
Q
When does a salt NOT affect pH
A
Cations from STRONG BASES
Anions of STRONG ACIDS
–> do not recombine with OH- or H+
JUST GO ONE WAY
4
Q
How to figure out base/acid strength
A
Strong acid –> weak conjugate base
Weak acid –> strong conjugate base
5
Q
When do salts produce acidic solutions
A
Salt:
Anion –> NOT a base
Cation –> conjugate ACID of weak base
6
Q
When both ions have basic and acidic properties, how do you determine if acidic or basic?
A
Find Ka and Kb of each ion (whichever is larger)
