Question

give the role of anhydrous calcium chloride in the process of roasting ​

Answer 1

Explanation:

It strongly absorbs water. Very useful for drying water out of a cell phone that gets wet accidentally. One of the most common uses of anhydrous calcium chloride is as a drying agent (dessicant). It absorbs water from the air (hygroscopic).

This helps to keep water away from the reaction mixture, which would destroy the Grignard reagent. used as a drying agent. The anhydrous calcium chloride tube is placed between the reaction vessel and the atmosphere. This is to prevent any moisture from getting into the reaction vessel.

Answer 2

Answer:

The anhydrous form of calcium chloride may also be used for this purpose and can provide a measure of the moisture in concrete. ... CaCl2 acts as flux material, decreasing the melting point, in the Davy process for the industrial production of sodium metal through the electrolysis of molten NaCl.
