You can label the test tubes with the names or letters like A,B and C. The difference can be seen from looking at the test tubes. However; there are also tests that can help you differentiate between different substance.

∙ 13y agoIf a mixture of A+B, A+C, or B+C is made, a depression of melting point will prove whether or not two compounds having the same melting points are identical. If the two substances in the mixture are identical, the mixture will have the same melting point. If the two substances in the mixture are different, the mixture will have a reduced melting point.
