a) 2 moles of solute dissolved in 3 liters of solution
b) 4 moles of solute dissolved in 8 liters of solution
a -- 2 moles of solute dissolved in 3 liters of solution
contains the maximum amount of dissolved solute for a given amount of solvent at a specific temperature and pressure.
Saturated solution
is a mixture containing particles that settle out if left undisturbed.
What is Suspension?
If 45 mL of water are added to 250 mL of a 0.75 M K2SO4 solution, what will the molarity of the diluted solution be?
0.64M
What group is always soluble no matter what?
Group 1
Why is Milk not considered a solution?
It is not transparent and light is dispersed within.

4 Liters
Another name for a solution
homogenous mixture
dispersed colloid particles scatter light, a phe-nomenon
What is Tyndall effect?
If you dilute 175 mL of a 1.6 M solution of LiCl to 1.0 L, determine the new concentration of the solution.

What does "like dissolves like" mean? Explain in terms of polarity and ionic.
Like dissolves like means that soluteswith the same polarity (polar or nonpolar) as the solvent will dissolve in the solvent. Ionic will dissolve in polar solvents.

C: Solution
A: Shows tyndall effect but not filtration
B: shows tyndall effect and filtration
C: Does not show tyndall or filtration
