COPPER (II) SULPHATE 5.H2O crystals
Copper(II) sulfate (CuSO4), is a common salt of copper. Copper sulfate exists as a series of compounds that differ in their degree of hydration. The anhyrdous form is a pale green or gray-white powder, while the hydrated form is bright blue. The archaic name for copper(II) sulfate is "blue vitriol" or "bluestone"
How to use copper sulphate for killing Moss:mix 5-8g per litre of water. apply this solution at a rate of 1 litre per 5m2.
How to use copper sulphate for treating algae in ponds, fish tanks and aquariums:
Dissolve 30g of copper sulphate and 30g of citric acid in 1 litre of water. For each 5 litres of pond water add 1 drop of the made up solution (this equates to 0.15ppm). Do not allow levels of copper to exceed 0.20 ppm.
Several chemical tests utilize copper sulfate as an indicator. In a flame test its copper ions emit a deep blue-green light. It is used infehlings solution and Benedicts solution to test for reducing sugars, which reduce the soluble blue copper(II) sulfate to insoluble red copper oxide. Copper(II) sulfate is also used in the Biuret reagent to test for proteins.
Copper sulfate is also used to test blood for anemia. A drop of the patient\'s blood is dropped into a beaker of copper sulfate solution: if it sinks within a certain time, then the patient has sufficient haemogloblin levels and is not anemic. If the blood floats or sinks too slowly, then the patient is iron-deficient and may be anemic.
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. However due to its toxicity, it is not recommended for small children.
Copper sulfate is often used to demonstrate an exothermic reaction, in which steel wool or magnesium ribbon is placed in an aqueous solution of CuSO4.
It is used in school chemistry courses to demonstrate the principle of mineral hydration. The pentahydrate form, which is blue, is heated, turning the copper sulfate into the anhydrous form which is white, while the water that was present in the pentahydrate form evaporates. When water is then added to the anhydrous compound, it turns back into the pentahydrate form, regaining its blue colour.
It can be used to plate metals with copper.It finds use in agriculture as a fungicide. Mixed with lime it is called Bordeaux mixture, which is used to control fungus on plant leaves, grapes and other berries. Normally it is used as a 1% solution (100g copper sulphate & 100g Lime per 10 litres of water)
Its use as an herbicide is not agricultural, but instead for control of invasive exotic aquatic plants and the roots of other invasive plants near various pipes that contain water.
A very dilute solution of copper sulfate is used to treat aquarium fish of various parasitic infections, and is also used to remove snails from aquariums. However, as the copper ions are also highly toxic to the fish, care must be taken with the dosage. Most species of algae can be controlled with very low concentrations of copper sulfate.
Other uses include: hair dyes, as a fining in winemaking, and the processing of leather and textiles.
