are colorless.
Used paper chromatography of I used TLC paper as well as I could use HPLC
inks. I used tap water as the paper chromatography to chromatography which is the
solvent and the ink was extract plant pigments and process of separating
dispensed in a pen amino acids. I extracted plant components in a liquid mixture
pigments using pestle and using a column. This will allow a
mortar with an extraction quantitative analysis
solvent. I applied plant
pigments and amino acids using
a capillary tube.
I could measure solute and I can now identify unknown I can use different solvent
solvent distance molecules using known blends by using a blender. Using
molecules by measuring the a blender can be used to extract
solute and solvent. more plant pigments
We could use these chromatography skills in unit 4 when we look at the purity of an organic solvent. I
can also transfer these skills to unit 6 which is the project which might include chromatography.

Used a balance to weigh metal I can now calibrate a balance. A I could use a magnetic stirrer so

Calculate moles from a practice Standardized HCI using a Make a standard solution from
