Acid Base Properties of Salts Flashcards
1
Q
General facts about salts…
A
- It’s an ionic compund
- A cation comes from a base and an anion from acid
- When dissolved in water salts break up into ions
2
Q
Salts that produce Neutral Solutions
A
- Cations of strong bases
- Anions of strong acids
3
Q
When dissolved in water salts can either form…
A
- Acidic solutions
- Basic solutions
- Neutral solutions
4
Q
Salts that produce Basic Solutions
A
- Cation has neutral properties
- Anion is the conjugate base of a weak acid
5
Q
Salts that produce Acidic Solutions
A
- Anion has neutral properties
- Cation is the conjugate acid of a weak base
6
Q
Salts where Cations and Anions Hydrolyze
A
The effect on the salt depends on the Ka and Kb values of the acid and base
7
Q
If Ka>Kb…
A
Solution will be acidic
8
Q
If Kb>Ka…
A
Solution will be basic
9
Q
If Kb=Ka…
A
Solution will be neutral
10
Q
When do metal ions hydrolyze?
A
When they are triply or doubly charged
