Chapter 13: Properties of Solutions Flashcards
1
Q
What is the best way to maximize dissolved carbon dioxide gas in water?
A
Decrease temperature and increase CO2 pressure
2
Q
Ionic and Polar solutions dissolve in what type of solvent?
A
Polar
3
Q
Nonpolar solutes dissolve in what type of solvent?
A
nonpolar
4
Q
Can Polar (or Ionic) and nonpolar solutes and solvents be mixed?
A
No, they do not mix homogeneously
5
Q
How does temperature affect solubility for solids and gasses?
A
- Most solids are more soluble in water at higher temperatures
- gasses are less soluble at higher temperatures (thermal pollution)
6
Q
How does pressure effect gas solubility?
A
They are proportional; solubility increases as the pressure increases
7
Q
Why does NaCl dissolve in water?
A
Because of the ion-dipol attractive forces
