Solubility Flashcards
1
Q
What is the only thing that can change the constant Ks
A
Temperature
2
Q
Name 3 ways to change solubility
A
- Add a solution that contains one of the ions present in equilibrium
- Change the pH of the solution
- React one of the dissolved ions in a secondary reaction
3
Q
If two solutions are mixed together, the concentrations of the dissolved ions will change because the volume changes. The new concentration can be calculated by:
A
[new]=[old] X DF
4
Q
How to calculate DF
A
Initial volume/total volume
5
Q
If Q=K
A
Reaction is at equilibrium
6
Q
If Q>K
A
Products are greater that it should be so reverse reaction is favoured.
7
Q
If Q<K
A
Reactants are greater than they should be so forward reaction is favoured
8
Q
Q=Ks
A
Solution is saturated
9
Q
Q>Ks
A
Precipitate will form
10
Q
Q<Ks
A
No precipitate will form
