Explain how individual gases can be separated from a gaseous mixture of O_2, H_2 and CO_2. |
| Answer» Solution :When a MIXTURE of `O_2, H_2 and CO_2` is present, the mixture can FIRST be passed through KOH as it will dissolve the `CO_2`. This `CO_2` can be obtained BACK from KOH by adding dilute HCl.The left over mixture contains `O_2 and H_2`. As the molucular weight difference is HIGH, therefore, they can be separated by DIFFUSION, where `H_2`will come out first. | |
