10 Things to Know About Copper(II) Chloride

copper(II) chloride

 

When we think of copper, we often think of shiny pennies or pipes at the hardware store. But copper has many uses beyond coins and pipes. 

 

Several copper compounds exist, each used for a multitude of purposes. One of the most interesting copper compounds is copper(II) chloride. Its surprising uses and fascinating properties make it worth a second look. 

 

Here are 10 things to know about copper(II) chloride.

 

Water content determines copper’s color.

Copper(II) chloride that contains no water molecules, the anhydrous form, is a yellowish-brown powder. When it does contain water molecules, in the dihydrate form, it is a green crystalline solid.

 

Copper helps us celebrate the Fourth of July.

Copper(II) chloride is used in the production of fireworks. It creates the blue and green hues that paint the sky during our most explosive celebrations. 

 

It can protect your next woodworking project. 

Copper(II) chloride can be used to protect wood from mildew and rot. In fact, you can purchase wood treatment products that contain the compound. It is often used on fences and greenhouses. The copper(II) chloride even leaves a green finish.

 

Hospitalized patients sometimes get copper injections. 

Patients receiving total parenteral nutrition (TPN), a feeding system that bypasses the gastrointestinal system, are often injected with copper(II) chloride. In patients on TPN, the copper compound keeps red and white blood cell count high and prevents secondary iron deficiency and osteoporosis.  

 

Copper is a fashionista’s best friend.

Fabric does not dye easily. To get a wide range of vibrant colors, fabric manufacturers use copper(II) chloride as a dyeing mordant. It helps set the dyes into the fabric. 

 

When metal and chlorine meet they become something special.

When chlorine atoms connect with metal, like in copper(II) chloride, it is called an inorganic chloride. 

 

Copper brought photography to life before the digital age. 

Before digital cameras were the mainstay of photography, photographers relied on chemistry to capture precious moments. Copper(II) chloride was used to develop pictures in the photo lab and is still used today by photographers who prefer film. 

 

Copper helps make PVC.

Copper(II) chloride is used as a catalyst in many types of organic chlorination reactions. One example is in the production of vinyl chloride, the foundation of PVC before it is polymerized

 

Fire can change copper(II) chloride.

Copper(II) chloride is not flammable. But when it is ignited it can become hydrogen chloride gas.  

 

Copper can help us monitor humidity. 

Humidity indicator cards (HICs) use chemistry to monitor the humidity in sealed product packaging. Until the late 1990s, HICs were exclusively made using cobalt(II) chloride. But in 1998, the European Community declared cobalt(II) toxic and HIC manufacturers turned to copper(II) chloride as a nontoxic alternative.
