If you've ever seen a bluish color on a penny, it's probably copper acetate.When copper reacts with acetic acid, it forms fine blue copper acetate crystals.You can make copper at home or in the lab.You don't need a lot of scientific background to make this chemical.
Step 1: acetic acid and hydrogen peroxide should be mixed together.
There is a household version of acetic acid.It is a form of acetic acid that can be found in many home chemistry experiments.It's best to mix it with hydrogen peroxide in a brown plastic bottle.The mixture should be 50%.If you use 1 cup of hydrogen peroxide, use the same amount of vintner.It is a good idea to use plain white vinegar.Gloves and goggles are required for dealing with acids and oxidizers.They shouldn't be on your skin or in your eyes.
Step 2: The solution should be in a glass container.
Bringing the solution to a boil takes the guessing out of it.The solution can be put on the stove in a glass container.It is ready to form copper acetate when it is at a boil.
Step 3: Add copper to the solution.
To supply copper for the reaction, use copper wire or a penny.Don't touch the hot solution or splash yourself if you lower the copper into it.If the solution splashes, you should be wearing gloves and goggles.If you are using a penny, you should only use pennies that were issued in 1982.After that, pennies have been made from copper plated zinc and only 2.5% of copper.
Step 4: Listen to the reaction.
The solution to change color needs to be watched.A blue color shows that copper has formed.It should happen in a few minutes.If the solution does not turn blue, copper did not form.Check your reagents.Make sure the chemicals aren't expired and that the proportions are correct.Make sure your copper source is truly copper and not just another metal plated with copper.
Step 5: It is possible to make calcium acetate.
Add calcium carbonate to water.When the calcium carbonate is dissolved, mix it.The main ingredient in chalk is calcium carbonate, so it is not necessary to order it from a chemical supplier.It's a good idea to use plain white vinegar.You can make calcium carbonate by grinding up chalk.While working with acids, gloves and goggles should be worn.You can use half as much calcium carbonate as you like.If you use 2 cups of vinegar, use 1 cup of calcium carbonate.
Step 6: The calcium acetate should be added to the copper sulfate solution.
You can find copper sulfate at a home and garden store.It is often referred to as a fungicide.It may be called a stump killer.It is in the water.Slowly pour the solution until it turns blue.The blue color indicates that you have made something.The solution should be blue.Gloves and goggles are required to avoid getting the solution on your skin or eyes.
Step 7: The solution should beFILTERED.
The blue solution has dissolved copper.calcium sulfate will be a solid that comes out of the solution.To remove the calcium sulfate, pour the solution through a strainer.You will get a blue copper solution.Wear goggles and gloves when handling calcium sulfate as it can cause irritation to the skin and eyes.If you get any on your skin, wash it with soap and water.If you see it in your eyes, wash them with warm water for at least 15 minutes.If the container is in good shape and has a sealed lid, you can safely dispose of small amounts of calcium sulfate in a regular trash container.Saving calcium sulfate can be used in other experiments, such as heating with charcoal to produce calcium sulfide.
Step 8: Dissolve copper in water.
The pellets can be ordered online or at a chemical supply store.They should be dropped into warm water.The water should be stirred with a glass stirring rod.The solution needs to be blue.This step is not needed if you have made your own solution from household chemicals.
Step 9: Contribute to the precipitation.
There will be copper acetate.The solution can be left in a dry place.The water will be forced out of solution as it evaporates.There are blue crystals on the surface of your dish.Dropping a crystal in the solution will jump-start the precipitation.The solution shouldn't be accessible to small children and pets.Pets and small children may ingest the solution if left unattended.Acute copper poisoning can be dangerous or even fatal.
Step 10: The crystals need to be dry.
Pour off any remaining solution once you have obtained crystals.The crystals should be transferred to a paper towel.They should sit for a day or two to dry out.
