What is fractional distillation
Separating liquids dissolved in liquids or separating 2 substances with similar boiling points
What is a fractional column
A column full of glass beads with the highest temperature at the bottom
What happens to the substance with the higher boiling point?
It goes to the column as vapour and then trickle down as liquid as the temperature gets cooler as it rises
What happens to the lowet boiling point substance
It passes through beads through the condenser collected at another beaker as a liquid
What can some compounds in a mixture do?
Dissolve better than others in a solvent
What is solubility?
How much the substance is able to mix in a liquid
How does chromatography work?
Pencil line drawn on the bottom of paper with ink dots on it, paper grazes the water and over time the paper will absorb the water and the rate of solubility in each ink would show
How can you tell if a substance has a higher rate of solubility?
It travels higher up in the paper
Do you have to use only water as the solvent?
No
Why is the line in chromatography in pencil
Because pencil doesnt dissolve in water
