In Fischer-Ringe's method of separation of nobles gas mixture from air ............. is used
- A \(90 \% \mathrm{CaC}_2+10 \% \mathrm{CaCl}_2\)
- B coconut charcoal
- C soda lime + potash solution
- D \(90 \% \mathrm{CaCO}_3+10 \%\) urea
Answer & Solution
Correct Answer
(A) \(90 \% \mathrm{CaC}_2+10 \% \mathrm{CaCl}_2\)
Step-by-step Solution
Detailed explanation
In Fischer Ringe's method, air free from moisture and \(\mathrm{CO}_2\) is passed over a heated mixture \(\left(800^{\circ} \mathrm{C}\right)\) of \(90 \%\) \(\mathrm{CaC}_2+10 \% \mathrm{CaCl}_2\) in an iron tube, when following reactions take place…
