Video advice: Preparation of Copper Sulfate Crystals

This video demonstrates how to make pure, dry crystals of copper(ii) sulfate (CuSO4). A typical 5-mark exam question would go as follows:


Copper sulfate is a chemical compound with the formula CuSO4 and can be made in a chemistry laboratory by reacting copper oxide with sulphuric acid. Copper sulfate has many uses, from a fungicide and herbicide in agriculture, to creating the vivid blue colors in fireworks or for use in copper plating. Copper sulfate is acidic and should be handled with care due to its toxicity. Although a common component in school science lessons, students should be carefully supervised when working with copper sulfate solution. Put on safety goggles, and place the Bunsen burner on a heat-proof mat underneath a tripod. Check that the air hole on the Bunsen burner is fully closed, and turn on the gas tap. Light a splint and hold it two inches over the top of the Bunsen burner to ignite the gas. Pour 20 cm3 of the dilute sulphuric acid into the beaker. Open the air hole on the Bunsen burner to give a blue flame, and place the beaker on the tripod. Heat the sulphuric acid until almost boiling. Add a small amount of the copper oxide powder into the beaker using a spatula.

What to Do to Prepare Copper Sulfate at Home

How to make copper sulfate or copper sulfate from copper and sulfuric acid; this particular method uses basic electrochemistry.

You are able to boil the copper sulfate means to fix recover your copper sulfate. Since the solution contains sulfuric acidity, you will not have the ability to boil the liquid off completely (and you have to try not to touch the liquid, that will become concentrated acidity). The copper sulfate will precipitate out like a blue powder. Pour from the sulfuric acidity and reuse it to create more copper sulfate!


Video advice: How to prepare 0.1 M Copper Sulphate solution.


When you run electricity through copper electrodes which are separated from each other in a dilute sulfuric acid bath the negative electrode will evolve bubbles of hydrogen gas while the positive electrode will be dissolved into the sulfuric acid and oxidized by the current. Some of the copper from the positive electrode will make its way to the anode where it will be reduced. This cuts into your copper sulfate yield, but you can minimize the loss by taking some care with your set-up. Coil the wire for the positive electrode and set it at the bottom of your beaker or jar. Slip a piece of plastic tubing (e. g., a small length of aquarium hose) over the wire where it extends up from the coil to keep it from reacting with the solution near the anode. (If you had to strip your wire, leave the insulating coating on the part that runs down into the liquid). Suspend the negative copper electrode (anode) over the cathode coil, leaving a good amount of space. When you connect the battery, you should get bubbles from the anode, but not the cathode.

How to Manage Pests

Slaked lime is prepared by adding “quick” (hot, burned) lime (calcium oxide) to water to produce calcium hydroxide. Slaking quick lime in water can produce heat sufficient to boil the water, so regulate the amount of lime you add to the water at any one time, so the mixture doesn’t splash. Wear goggles or safety glasses to protect your eyes and stir the mix with a wooden stick while adding the lime to the water. The slaking chemical reaction takes 1/2 to 2 hours, so prepare the lime mixture before you plan to spray.

[FAQ]

How do you mix copper sulphate with water?

Application by Spraying Solution on Water Surface: Dissolve the minimum required dose of Copper Sulfate in water and spray the solution uniformly over the body of water. When spraying a solution of copper sulfate, mix copper sulfate in sufficient water to thoroughly spray the water surface.

What is a copper sulfate solution?

Cupric sulfate is a salt created by treating cupric oxide with sulfuric acid. This forms as large, bright blue crystals containing five molecules of water (CuSO4∙5H2O) and is also known as blue vitriol. The anhydrous salt is created by heating the hydrate to 150 °C (300 °F).

How do you make copper sulfate spray?

Use a ratio of 1 gallon of water, 3 1/3 tablespoons of copper sulfate, and 10 tablespoons of hydrated lime for each gallon of spray mixed. Start flowing water into the spray tank.

How do you mix copper sulfate in a pond?

You would mix 5 pounds of granular copper sulfate with 3 gallons of hot water, then spray it over half of your pond, wait a few days, and spray the other half. Never treat the entire lake or pond at once, as doing so will deplete oxygen levels while vegetation and algae decomposes after dying.

How can I make copper sulfate at home?

Make Copper Sulfate

  1. Fill a jar or beaker with 5 ml concentrated sulfuric acid and 30 ml of water. ...
  2. Set two copper wires into the solution so that they are not touching each other.
  3. Connect the wires to a 6-volt battery.
  4. The solution will turn blue as copper sulfate is produced.
