Ch 14 Mixtures and Solutions

Big Idea:Nearly all of the gases, liquids and solids that make up our world are mixtures.

I CAN:• Describe the concentration of solutions

using different units;• Compare properties of suspensions,

colloids and solutions;• Determine colligative properties of a

solution

∆Tb = Kb x m x i

∆Tf = Kf x m x i
