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 |
|
|
Why do wr use chromatography |
Separate compounds of a mixture To find out the rate of solubility from different compounds of different mixtures |
