Which of the following is not the application of adsorption?
- A Use of \(\mathrm{SiO}_2\) gel for removing the moisture
- B Use of coconut charcoal to separate inert gases
- C Use of \(\mathrm{Al}_2 \mathrm{O}_3\) to separate the components of organic mixture in chromatography
- D Use of \(\mathrm{CaCl}_2\) for removing the moisture
Answer & Solution
Correct Answer
(D) Use of \(\mathrm{CaCl}_2\) for removing the moisture
Step-by-step Solution
Detailed explanation
\(\mathrm{CaCl}_2\) is hygroscopic in nature and it absorbs moisture rather than adsorbing it on its surface.
