Decolorization

The document outlines Experiment No. 3 focused on the process of decolorization, which involves removing colored impurities from solutions using activated carbon or bone black. It details the procedure of dissolving brown sugar in water, filtering, and then treating half of the filtrate with activated carbon to compare color changes. The document also includes sections for recording observations, conclusions, and generalizations related to the experiment.

Experiment No.

Decolorization

Discussion:

Decolorization is defined as the process of removing colored impurities in the solution.


This is done by mixing organic compound with activated carbon or bone black usually with
heating and continuous stirring. The fine carbon particles have a large active surface that
readily attract and absorb reactive impurities found in organic mixtures. The amount used
should be 2-3% of the weight of the sample. Any excess will only absorb part of the product
that may result in a lower yield.

Procedures:

Dissolve 4 grams of brown sugar in 30 mL of water. Filter and save one-half of the
filtrate for comparison. To the one-half, add a tiny pinch of black and gently boil the mixture for
20-30 minutes. Filter repeatedly if necessary and compare the color of the filtrate with that of
the original.
