What is chromatography |
Method used to separate a mixture of soluble substances and identify them |
|
|
In chromatography what is the mobile phase |
Where the molecules can move The mobile phase in chromatography is the solvent |
|
|
In chromatography what is the stationary phase |
When molecules can’t move In chromatography the stationary phase is the filterpaper |
|
|
How do you set up chromatography |
Draw a line near the bottom of filterpaper it’s the baseline use pencil Put a spot of mixture to be separated on the line put solvent into beaker dip bottom of paper but not spotted the solvent solvent will move up the paper when the chemicals dissolve in the solvent As they move up the paper you will see the different chemicals in the sample separate out forming spots in different places on the paper |
