Question

The statement given below is incorrect. Write the correct statement.

Iodine is removed from the mixture of iodine and sand by the process of evaporation.

Answer 1

• Evaporation: The process in which a liquid changes into a gaseous state on gentle heating, such that liquid does not boil, is called evaporation.
• The process of evaporation is used to remove soluble solids from their solution in water.
• Sublimation: This method is used when a mixture consists of two or more solids, in which one of the solid sublimes on heating.
• A mixture of iodine and sand can be separated by sublimation as iodine can sublime.

• Therefore, the correct statement is:

Iodine is removed from the mixture of iodine and sand by the process of sublimation.
