Faahfaahinta casharka

Natiijada casharka

I can describe how chromatography works and use a chromatogram to answer questions about a substance.

Muuji qoraalka
Chromatography can be used for both separation of minute samples and analysis. A pure substance will only produce one spot on a chromatogram. A mixture will produce many spots on a chromatogram. Comparing chromatograms can help to identify an unknown component in a sample. Pencil is insoluble in water.

    • Waxay soo saartaa dhibco badan (multiple spots).
    • Ma dhaqaaqdo.
