Ethanedioc acid is used instead of methanoic acid to prepare carbon 2 oxide in the labolatory. It gives equal volume of carbon 2 oxide and carbon 4 oxide. If water is one of the products write a word equation for the dehydration of ethanedioc acid.
(B) How can pure carbon 2 oxide be obtained from the mixture of two gases?
To answer the first part of your question, we need to understand the process of dehydration, which involves the removal of water from a compound.
The word equation for the dehydration of ethanedioc acid can be written as follows:
Ethanedioc acid → Carbon dioxide + Carbon monoxide + Water
Now, let's move on to the second part of your question, which asks how to obtain pure carbon 2 oxide (carbon monoxide) from a mixture of two gases.
To separate the mixture of carbon dioxide and carbon monoxide and obtain pure carbon monoxide, you can use a process called fractional distillation. This process takes advantage of the different boiling points of the two gases.
Here's a step-by-step guide on how to obtain pure carbon monoxide:
1. Collect the mixture of carbon dioxide and carbon monoxide in a container.
2. Pass the mixture through a purification system to remove impurities such as water vapor and other gases.
3. Next, cool down the gas mixture to a low temperature using refrigeration techniques.
4. Once the gas mixture is cold, introduce it into a fractional distillation apparatus. This apparatus consists of a fractionating column, which is a long vertical tube with several trays or chambers.
5. Apply heat at the bottom of the fractionating column, and the gases in the mixture will start to vaporize. Carbon monoxide, having a lower boiling point (-191.5°C), will vaporize and rise up the column more readily than carbon dioxide. This is because carbon dioxide has a higher boiling point (-78.5°C).
6. As the gas mixture vaporizes and rises up the column, it will start to condense on the trays or chambers within the column.
7. The trays or chambers are designed to have different temperatures, gradually decreasing from the bottom to the top. This temperature gradient helps to separate the carbon monoxide and carbon dioxide further.
8. The carbon monoxide, being the lower boiling point gas, will condense and collect in a specific chamber lower in the column, while the carbon dioxide will continue to rise to a higher chamber.
9. Finally, you can collect the carbon monoxide from the designated chamber, resulting in the isolation of pure carbon monoxide.
By applying fractional distillation, it is possible to obtain pure carbon monoxide from a mixture of carbon dioxide and carbon monoxide.
