    Disperse Red 9 Lab Report

    • 322 Words
    • 2 Pages

    Discussion: The two dyes identified were disperse blue 3 and disperse red 9. Disperse red 9 separated first because it is less polar than disperse blue 3. This is due to the structure of disperse red 9 being more symmetrical than that of disperse blue 3 and having more nonpolar bonds. Disperse blue 3 is more polar because it has a hydroxide bond and has a larger dipole. The principle behind using column chromatography is that it separates compounds based on polarity. The alumina serves to allow

    EXPERIMENT 5: CHROMATOGRAPHY Abstract Paper Chromatography uses a chromatogram paper as its stationary phase and the solvent as the mobile phase. Retention factor is the ratio of the distance travelled by the sample to the distance travelled by the solvent. This experiment aims to separate organic compounds‚ to compute Rf values and to identify unknown compounds using Rf values. The ten samples underwent paper chromatography to determine the components of the unknown sample. The mobile phase allowed
