Tellurium Dioxide TeO2

Tellurium dioxide is known in two different crystalline forms. Crystals of the tetragonal system but almost regular (a c = 1 1.1076) of density 5.66 are obtainable from the solution in nitric acid while the molten dioxide when slowly cooled deposits rhombic needles (a b c = 0.4566 1 0.4693) of density 5.93 and identical with the rarely

How could you separate lauric acid from alpha naphthol

The melting point for lauric acid is about 45 degrees while it is 121 degrees for naphthol. So in a mixture repeated cycles of slow warming and cooling should separate out lauric acid from naphthol. We can improve the efficiency by adding a dash of slightly acidic 70 isopropyl alcohol.

Chemical Properties of Tellurium

On warming tellurium dioxide and sulphur dioxide are produced. If the sulphuric acid is hot and concentrated a red solution is obtained from which tellurium may be separated by the addition of water.
