Moisture in the environment can become a serious problem for various chemical experiments or production processes. There are a huge number of devices designed to remove humidity from the environment. These devices are known as dehumidifiers, some are of electrical origin and others are purely chemical, but they all have the same purpose. Today, we will look at how to make a homemade dehumidifier quite simple, which we can use to largely eliminate humidity from our work environment, study environment, or as a science project.
- Calcium chloride.
- An old lycra sock or stocking.
- A metal or wooden stand.
- A plastic container.
Setting up our dehumidifier
The first thing we are going to do is to take about 500 g of calcium chloride (usually in the form of small white balls), place it inside the sock (or stocking) and close it with a knot at the top.
Next, it is time to place the support inside the area where we want to remove the moisture. We place the sock filled with calcium chloride on top of this support.
The sock should be positioned so that it never touches the ground. Ideally, it should be at a distance of about 10 cm from the ground. Then, place the plastic container at the bottom of the support and just below the sock. In this way, we can collect the captured moisture.
Now, it only remains to wait a certain amount of time to see how much liquid can be collected. This quantity gives us an idea of the degree of humidity of the environment where it is installed. our dehumidifier.
How it works
The operation of the home dehumidifier is quite simple, calcium chloride is a hygroscopic substance, i.e. it is a substance that absorbs liquid from its environment. Thus, as it absorbs a certain amount of water from the environment, it disintegrates and the water will drip down through the media and gradually fall into the collection container.
We can see how a characteristic of an element can create a useful chemical reaction to improve the environment in which we find ourselves.
