Give two reasons why the crude product in most reactions is not pure.

Answer 1

1. inclusion of starting material
2. inclusion of side reaction material

Answer 2

One of the reasons that the crude product in most reactions is not pure is because the reaction is not complete and we have to do an additional step/steps of decolorization and crystallization to have a pure product that could be checked by its melting point

Answer 3

im not very sure about it...

Answer 4

Also because most of the times the crude product is only treated with water, which does not dissolve all the impurities found in the substance or mixture you started with.
