Document Summary

See chm1321 introductory organic chemistry laboratory manual 2017, pages 32 33. *modification: diethyl ether was used in place of ether. Diethyl ether is a clear colorless liquid that smells like nail polish remover. Until the dye was added to it, the difference between the two substances in the test tube with a mixture of 1ml diethyl ether and 1ml water was not distinguishable. Even before the dye was added to it, the difference between the two substances in the test tube with a mixture of 1ml diethyl ether and 2ml water was distinguishable. After the blue methylene dye was added to the test tube, and the tube was shaken, it settled in the lower aqueous layer. The blue dye was a deep, vivid, opaque blue. After the red methyl dye was added to the test tube, and the tube was shaken, it settled in the upper organic layer.
