No. The acetone serves as a heat exchange fluid._Anthony_ said:endothermic reaction
Zero for temperature difference; generally, evolution of heat for non-reactive dissolution of gases in a liquid phase. Misapplication of the phase rule, treating two phases instead of three, will result in very screwy descriptions of phenomena._Anthony_ said:It identifies a Heat of Solution as a contributor to temperature reduction. So the dissolution of CO2 in acetone is endothermic. At a temperature around -78C or so, how much?
Dry ice and acetone is a mixture of solid carbon dioxide (dry ice) and liquid acetone. It is commonly used in science experiments and demonstrations as it produces a thick white fog when the dry ice sublimates in the acetone.
The mixture of dry ice and acetone is considered endothermic because it requires energy to break the bonds between the molecules of carbon dioxide and acetone. This energy is absorbed from the surrounding environment, causing the temperature of the mixture to decrease.
The endothermic reaction of dry ice and acetone can be useful in scientific experiments as it allows for a controlled release of cold temperatures. It can be used to create a cold environment for preserving or freezing materials, or to demonstrate the principles of endothermic reactions.
The reaction between dry ice and acetone is generally considered safe when done in a controlled environment. However, precautions should be taken as the mixture can produce a large amount of carbon dioxide gas which can displace oxygen in a confined space. It is important to work in a well-ventilated area and to handle dry ice with protective gloves.
Yes, the dry ice and acetone mixture can be reused multiple times as long as there is still dry ice present. Once the dry ice has fully sublimated, more dry ice can be added to the remaining liquid acetone to create the fog effect again. However, the mixture should be disposed of properly once it is no longer needed, as the acetone can be hazardous to the environment if not disposed of correctly.
