If the mixture of carbon(II) oxide (CO) and carbon(IV) oxide (CO₂) is bubbled through lime water (Ca(OH)₂), it will selectively remove CO₂, but not CO.
Explanation:
CO₂ reacts with lime water to form calcium carbonate (CaCO₃), which is insoluble and forms a white precipitate:
CO_2 + Ca(OH)_2 → CaCO_3 ↓ + H_2O
CO does not react with lime water and will pass through, leaving behind pure CO.
Conclusion:
Bubbling the mixture through lime water is an alternative method for obtaining pure CO, similar to using NaOH, but NaOH is generally more effective because lime water can become saturated with CaCO₃, limiting its efficiency.
carbon monoxide(CO) is obtained from carbon dioxide (CO2)by reducing the CO2 with hot carbon.But the product formed would still contained some amount of unreacted CO2 as well as the CO. so in order to obtain pure CO , the product is passed through a strong alkali(NAOH).Since CO2 is acidic, it would react with the NAOH to form sodium carbonate (liquid)while the CO would be collected purely since it's neutral and wouldn't react with the NAOH.
myschool please the answer is wrong.
to obtain pure CO from CO2, u kindly dissolve it in the water under the pressure of 30 atm. hence, review it please. the correct answer is B.
