Pure and dry Air is passed over soda lime and potash solution and then through a long tube containing red hot copper. The remaining air is passed over heated magnesium ribbon
Which of the following are removed when air is passed through soda lime and potash

A

`O_2`

B

`N_2`

C

`CO_2`

D

`CO_2` and water vapour

Text Solution

Verified by Experts

The correct Answer is:
C
`2Cu + O_2 to 2CuO`
`3Mg + N_2 to Mg_3 N_2`
for complete removal of `O_2 and N_2` the air obtaned after removal of `CO_2 and H_2O` is repeatedly passed over heated Cu and Mg.
`C + O_2 to CO_2`
