Why During separation of carbon dioxide and water anhydrous calcium chloride is used ?
Answers
Explanation:
The invention relates to a carbon dioxide content determination apparatus. The apparatus comprises a reaction device, the reaction device comprises a reaction bottle, the reaction bottle is provided with a separating funnel having a piston, an alcohol burner is arranged under the reaction bottle, a device for absorbing carbon dioxide in air is arranged in front of the reaction bottle, and an impurity removal device, a carbon dioxide absorbing device and a water absorbing device are sequentially arranged behind the reaction bottle. The apparatus has the advantages of simplicity, easy operation, realization of the assembling completion in most laboratories, and wide application range. The carbon dioxide content result determined through using the apparatus is stable and reliable, and has a good precision and a good accuracy; and simultaneously anhydrous calcium chloride is used to substitute anhydrous magnesium perchlorate, so the measure cost is effectively reduced, and the apparatus is economic and practical.
