An Introduction to Sublimation in Chemistry
An Introduction to Sublimation in ChemistryThere are many great examples of sublimation in chemistry that you may not have known. It is a process that are used in all types of chemical reactions, but it is the one we are most familiar with today. As the name implies, sublimation is the transfer of a substance to another medium. Here are some examples of sublimation in chemistry that you may not have considered before.One example of sublimation in chemistry is the formation of alcohols or ketones from chlorinated compounds. This is common in organic chemistry as well as in thermodynamics. This is the way that a complex compound is formed when it comes into contact with both a strong solvent and a weak solvent at the same time.The process can also occur through a combination of carbon and oxygen atoms that bind together. The carbon atom and an oxygen atom are necessary for this process to occur. In other words, this is how the carbon is turned into carbon dioxide or carbon gas by anoth er reaction.Another example of sublimation in chemistry is the formation of the gas propane. It is very similar to other gases that we know of such as ethane or even butane. The only difference is that the above-mentioned two do not exist in pure form and must be created through a more complex process. This process is quite complex and involves the use of a catalyst.For example, the gas carbon dioxide can be turned into carbon monoxide through this same reaction. It will take longer to do it, but this is what we are talking about. Another example of sublimation in chemistry that you might not have considered involves the reaction of an acid with water. This process is referred to as hydrolysis.This is the process where an acid reacts with water to create HHO, which is a very simple type of chemical reaction. Hydrolysis is not the only example of sublimation in chemistry, though. We have seen the reduction of chlorides to sodium chlorate, which is also a simple process. To get to the solution that you are looking for, you need to go back and look at these examples.Another important thing to know about the process of sublimation in chemistry is that the reaction that we describe here is what is called a nonthermal reaction. It does not involve heat, and that is why it is used as a 'reference' method in thermodynamics. Because of this, it makes sense that the rate of the reaction will not change even if the temperature of the solution increases.That is why these are called reference methods. They are used to give us a starting point for our calculations. In chemistry, the period of time that a reaction takes is known as its time constant. The more precise term is the time-averaged half-life.
