Topic: Copper(II) sulfate

In the News (Fri 25 Apr 14)

  Copper Sulfate
Copper sulfate is a naturally-occurring inorganic salt and copper is an essential trace element in plant and animal nutrition (5, 6, 7, 13, 16).
When copper sulfate is given intravenously, or injected into the vein, as little as 2 mg/kg copper sulfate is lethal to guinea pigs; and 4 mg/kg is lethal to rabbits (13).
Although copper sulfate is highly water soluble-that is, it dissolves very easily in water-the copper ions are strongly adsorbed or precipitated to soil particles when it is applied to soil (13).

 Copper(II) sulfate - Wikipedia, the free encyclopedia
Copper sulfate exists as a series of compounds that differ in their degree of hydration.
It is made by the action of sulfuric acid on a variety of copper(II) compounds, such copper(II) oxide and copper carbonate.
Copper sulfate is a commonly included chemical in children's chemistry sets and is often used in high school crystal growing and copper plating experiments.

_______________________________________________________________________ [2] (c) Strong heating of aqueous copper(II) sulfate, in a distillation apparatus, results in the quantitative recovery of copper(II) sulfate, as an off-white solid, and water, as a colourless liquid:
Probably the most familiar example of a copper(I) compound is that observed when a positive result is obtained in the Fehling's test for 'reducing sugars'; e.g., warming an alkaline solution of glucose and copper(II) sulfate results in the precipitation of copper(I) oxide as a pale-orange solid.

Results The combinations of starting material and reducing metal that worked best for us were copper (II) sulfate and zinc, as used by the CSB/SJU general chemistry lab, and the copper (II) chloride and aluminum foil (see data table).
The advantages of using the copper (II) sulfate - zinc combination are that copper (II) sulfate is relatively safe to use and that good results can be obtained.
Student Procedures for using the reduction of copper as a stand-alone lab exercise The following are two procedures for using the last phase of the copper cycle lab as a stand-alone lab exercise for high school students.

 Copper sulfate electrolysis   (Site not responding. Last check: 2007-10-13)
Other equipment needed: one 10 mL conical flask, a few centimetres of clean copper wire approx 1 mm diameter, concentrated copper sulfate solution (at least 1M), cotton wool, source of low-voltage DC current, with potentiometer to regulate cell voltage, electric leads, voltmeter (or multimeter) to monitor cell voltage.
If a solution of copper(II) sulfate is electrolysed with a platinum anode, oxygen will be produced at the anode, while copper is deposited at the cathode.
The mass of the whole electrolytic cell should decrease by the mass of the oxygen given off, while the mass of the cathode should increase by the mass of copper ions reduced.

In order to reduce copper(II) sulfate to copper metal, 1.2-1.4 g of zinc metal are added to the blue copper(II) sulfate solution from the previous step.
Immediately the zinc begins to react with the copper(II) sulfate, producing a dark solid, and the excess sulfuric acid, producing hydrogen gas (which causes the fizzing visible in this picture).
Because hydrogen gas is explosive, the beaker should be placed under a fume hood for the duration of the reaction.

 CR Scientific: Experiments: Cupric Sulfate and Sodium Thiosulfate
The first one involves an equimolar ratio of copper sulfate to sodium thiosulfate; the second uses an excess of sodium thiosulfate.
It is likely that sulfate anion itself remains unchanged; cupric ion in solution needs an anion to go with it, and the only ones present in solution were sulfur-based.
It might be instructive to repeat the experiment with cupric chloride instead of cupric sulfate.

 Copper Sulfate Color   (Site not responding. Last check: 2007-10-13)
You have also written the name copper(II) sulfate which indicates that the copper is in a cationic form of Cu2+ (the copper metal has lost two electrons), and the sulfur is in an anion complex of sulfate (SO4 2-).
Thus, neither the copper nor the sulfur is in its atomic form.
Further investigations reveal that sulfate containing compounds (sulfuric acid, iron(II) sulfate, sodium sulfate, etc.) are not blue.
