Copper sulfate will kill not only roots growing in the sewer line but also the organisms which produce offen sive odors. tree roots in contact with or immersed in copper sulfate solution absorb copper for a short distance into the root system. use of this treatment has yet to cause the loss of a tree or shrub. how do you make copper sulphate.
Copper sulphate is widely used as a fungicide, either alone or in association with other fungicides maneb, zineb, for the treatment of orchards and vineyards. it is sprinkled as a solution at about 1 , and in much more concentrated solutions if spread by plane.
Copper sulphate stains can be removed from cotton with peroxytype stain removers. it and take weeks to come out from under your fingernails, so i recommend wearing gloves. on the plus side, copper sulphate is a traditional antifungal treatment for skin which is why pharmacies stock it. instructions make a supersaturated solution.
Dissolve 70g copper sulfate per 100 ml water instead of 55g to grow single crystals. to achieve this, your water must be very hot. if not all of the powder manages to dissolve, you can reheat the solution, but be sure not to boil it. this is because boiling causes the compound to decompose. it takes some time to dissolve 70g in 100ml of water.
How do you make copper sulphate? make copper sulfate fill a jar or beaker with 5 ml concentrated sulfuric acid and 30 ml of water. set two copper wires into the solution so that they are not touching each other. connect the wires to a 6volt battery. the solution will turn blue as copper sulfate is produced.

How to make copper sulphate soluble salt from an insoluble base copper oxide and sulphuric acid? method 1. pour 25 cm 3 of sulfuric acid into a beaker. 2. add in excess copper ii oxide. 3. heat the beaker and stir until reaction is complete. 4. filter off the unreacted solid, collecting the clear blue solution in an evaporating dish. 5.
How to make sulfuric acid by electrolysis of copper using an inert anode. copper sulfate is very easy to obtain in large quantities at gardening and hardware stores and provides a convenient route to sulfuric acid if the appropriate anode can be obtained. warning this should be done in a wellventilated area as hydrogen gas build up is explosive.
In a container with diluted sulphuric acid add some water if necessary place two copper wires connected to a 6volt battery. its important to make sure the copper wires do not touch each other. the solution very quickly turns blue, as the reaction occurs to produce copper sulphate. cu 2 h2so4 cuso4 so2 2 h2o.
It can make water runoff hazardous. copper sulfate is known to build up once used, and can cause runoff water to become potentially hazardous to those who encounter it. water that has been contaminated with copper sulfate can be harmful to crops, animals, and people. for this reason, copper sulfate is an unnecessary danger.
