Glycerine is purified by
Options
(a) vacuum distillation
(b) simple distillation
(c) steam distillation
(d) sublimation
Correct Answer:
vacuum distillation
Explanation:
The compounds which decompose at a temperature below their normal boiling points cannot be purified by distillation under ordinary atmospheric pressure. For such compounds, distillation is carried out under reduced pressure and the process is known as vacuum distillation. Glycerine is one such compound which is purified by this method.
