Answer to Question #296749 in Organic Chemistry for Eman

Question

Is carbon soluble in any of these solvents?Write very soluble, slightly soluble, not soluble at all, and the reasons.

• Water
• Hydrochloric acid
• Sodium hydroxide
• Oil
• Chloroform

Answer 1

1.for water

Although carbon dioxide mainly consists in the gaseous form, it also has a solid and a liquid form. It can only be solid when temperatures are below -78 ^oC. Liquid carbon dioxide mainly exists when carbon dioxide is dissolved in water. Carbon dioxide is only water-soluble, when pressure is maintained.

2.Hydrochloric acid

The solubility of carbon dioxide in aqueous HCl and NaHCO3 solutions has been determined by the coulometric technique at ambient pressure and at 278, 283, 287, and 298 K. The error in CO2 solubility in HCl solutions estimated from parallel experiments was about 0.3%.

3.Sodium hydroxide

 that carbon dioxide does not dissolve in sodium hydroxide but it combines with sodium hydroxide to form sodium carbonate which has the ability to dissolve in water. Sodium carbonate is also known as Washing soda.

4.Oil

In spite of the low solubility of hydrogen in fatty oil, the differential heat of solution is larger than that of other gases. When carbon dioxide is dissolved in oil, the viscosity, or the flow out time of oil, decreases lineally as the amount of dissolved gas increases.

5.Chloroform

It is miscible with alcohol, benzene, petroleum ether, carbon tetrachloride, carbon disulfide and oils
