  2. Copper(II) sulfate - Wikipedia

    en.wikipedia.org/wiki/Copper(II)_sulfate

    Copper(II) sulfate is an inorganic compound with the chemical formula Cu SO 4.It forms hydrates CuSO 4 ·nH 2 O, where n can range from 1 to 7. The pentahydrate (n = 5), a bright blue crystal, is the most commonly encountered hydrate of copper(II) sulfate, [10] while its anhydrous form is white. [11]

  3. Copper(I) sulfate - Wikipedia

    en.wikipedia.org/wiki/Copper(I)_sulfate

    Copper(I) sulfate, also known as cuprous sulfate, is an inorganic compound with the chemical formula Cu 2 SO 4. It is a white solid, in contrast to copper(II) sulfate, which is blue in hydrous form. Compared to the commonly available reagent, copper(II) sulfate, copper(I) sulfate is unstable and not readily available. [1]

  4. Copper pesticide - Wikipedia

    en.wikipedia.org/wiki/Copper_pesticide

    Copper pesticides are copper compounds used as bactericides, algaecides, or fungicides. They can kill bacteria, oomycetes and algae, and prevent fungal spores from germinating. Common forms of fixed copper fungicides include copper sulfate , copper sulfate pentahydrate , copper hydroxide , copper oxychloride sulfate , cuprous oxide , and copper ...

  5. Copper toxicity - Wikipedia

    en.wikipedia.org/wiki/Copper_toxicity

    The suggested safe level of copper in drinking water for humans varies depending on the source, but tends to be pegged at 1.3 mg/L. [2] So low is the toxicity of copper that copper(II) sulfate is a routine reagent in undergraduate chemistry laboratories.

  6. Basic copper carbonate - Wikipedia

    en.wikipedia.org/wiki/Basic_copper_carbonate

    Basic copper carbonate is prepared by combining aqueous solutions of copper(II) sulfate and sodium carbonate. Basic copper carbonate precipitates from the solution, with release of carbon dioxide CO 2: [7] 2CuSO 4 + 2Na 2 CO 3 + H 2 O → Cu 2 (OH) 2 CO 3 + 2Na 2 SO 4 + CO 2. Basic copper carbonate can also be prepared by treating aqueous ...

    Copper sulfate may refer to: Copper(II) sulfate, CuSO 4, a common, greenish blue compound used as a fungicide and herbicide; Copper(I) sulfate, Cu 2 SO 4, an unstable ...

  8. Copper naphthenate - Wikipedia

    en.wikipedia.org/wiki/Copper_naphthenate

    Copper naphthenate is commonly prepared by treatment of naphthenic acid with copper(II) compounds such as basic copper carbonate or copper hydroxide. [1] Even copper(II) sulfate can be treated with sodium or potassium naphthenate in aqueous solutions.
