Once i reacted copper sulfate with sodium carbonate (double displacement) to get copper carbonate and sodium sulfate solution. There was a green suspension of copper carbonate in a clear solution of sodium sulfate. This time i did the same reactions, and i got blue fluff in a clear solution...
Copper, copper sulfate, sodium carbonate, turpentine, ethanol, and waterdoi:US20020031535 A1A topical formulation to treat skin conditions associated with skin cancer or other surface oriented skin disorders. The topical formulation includes the ingredients of copus or copper, bluestone, soda, ...
+ 2 H2O + 2 OH− Many other oxyanions form complexes; these include copper(II) acetate, copper(II) nitrate, and copper(II) carbonate. Copper(II) sulfate forms a blue crystalline pentahydrate, the most familiar copper compound in the laboratory. It is used in a fungicide called the Bordea...
we have our own manufactories for zinc sulfate, manganese sulphate and sodium metabisulfite. Meanwhile, we have reliable domestic suppliers, providing us with various high-quality chemicals, like copper(II) sulfate, lead(II) nitrate, magnesium sulfate, barium carbonate, ferrous sulfate, calcium chlori...
This coating of copper carbonate and copper sulfate provides a protective layer for the underlying metal that makes it ideal for use on boats, roofs, pipes, and coins.The surfaces of some copper church steeples and the Statue of Liberty have now oxidized toform a pleasing patina.One of ...

A variety of copper salts are suitably employed in the electroplating baths of the invention and include, for example, copper sulfate, copper acetate, copper fluoroborate, cupric nitrate. Copper sulfate pentahydrate is generally preferred. Similarly a variety of acids may be employed in the electropla...
(equation287),537,542(118) (equation288)539and (119) (equation289)543employed aqueous DMF as solvent and copper(II) chloride plus O2as the reoxidant. On the other hand, internal alkenes are normally not reactive under these conditions (cf.(119), equation289). Disubstituted α,β-...
awas made neutral to Congo red by the addition of 50 cc.of 2 N sodium carbonate which had been diluted to 100 cc. A solution of sodium arsenite was prepared by dissolving 30 g. of arsenious oxide in 300 cc. of 2 N sodium carbonate, and to it was added 2 g. of copper sulfate to...
a) Iron(III) nitrate and sodium carbonate. b) Copper(II) sulfate and sodium sulfide. Write the balanced molecular equation for the reaction that occurs between lead(II) nitrate and sodium sulfate. Write the net ionic equation for the reaction that occur...
