Colored molecules that absorb light are usually organic compounds that contain conjugated double bonds or transition metal ions in their structure. These molecules absorb specific wavelengths of light, causing them to appear colored. The absorption of light by these molecules leads to the excitation of electrons to higher energy levels.
Larger molecules will typically be located closer to the baseline of the chromatogram, as they move more slowly through the stationary phase on the filter paper and do not travel as far as smaller molecules during the chromatography process.
When iodine is mixed with water, it forms a solution that appears brown due to the interaction between iodine molecules and water molecules. The brown color comes from the absorption of light by the iodine molecules, which causes them to appear brown to our eyes.
Bleach turns things white by breaking down the molecules that give objects their color, making them appear lighter or white. This process is called oxidation, where the bleach removes the pigment molecules from the material, leaving it colorless.
When sugar dissolves in tea, it forms a solution and takes up space between the water molecules without significantly altering the volume of the tea. The sugar molecules integrate themselves within the spaces between the water molecules, which allows the tea to maintain its volume.
