If you have a mixture of CO and CO_(2), how would you know about the relative proportions of the two gases in the given mixture ? |

Answer» Solution :Pass mixture through the `CA(OH)_(2)` solution, `CO_(2)` is absorbed by `Ca(OH)_(2)`.The residual volume will be that of `CO` `Ca(OH)_(2)+CO_(2)toCaCO_(3)+H_(2)O` (ii)Pass mixture through `I_(2)O_(5),CO` reduces `I_(2)O_(5)` to `I_(2)`. `5CO + l_(2)O_(5) to I_(2)+5CO_(2)` `l_(2)` thus liberated is determined is determined by titration with `Na_(2)S_(2)O_(3)`. `2Na_(2)S_(2)O_(3)+l_(2)to2Nal+Na_(2)S_(4)O_(6)` This is the quantitative METHOD of estimation of `CO`. |
