Topic 8: Solutions

Question 1

solution

Answer 1

homogeneous mixture of a solute dissolved in a solvent

Question 2

solubility

Answer 2

ability to dissolve
depends on temp, pressure, and nature of solute and solvent

Question 3

“like dissolve like” means…

Answer 3

polar dissolves polar
nonpolar dissolves nonpolar
-nonpolar and polar DO NOT mix

Question 4

which types of solvents do ionic compounds dissolve in (polar or nonpolar)

Answer 4

POLAR bc..
POS ion attracts to the NEG end of polar molecule and vise versa

Question 5

which types of solvents do covalent compounds dissolve in (polar or nonpolar)

Answer 5

NONPOLAR bc…
covalent compounds are less polar so they are soluble in nonpolar solvents (like dissolves like)

Question 6

How will adding a solute to a solvent affect boiling and freezing points?

Answer 6

-HIGHER boiling point
-LOWER freezing point

Question 7

What does it mean if saturated solutions always exist in equilibrium?

Answer 7

rate of crystallization=rate of dissolving
