  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. Iron(II) sulfate - Wikipedia

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

    All the iron(II) sulfates dissolve in water to give the same aquo complex [Fe(H 2 O) 6] 2+, which has octahedral molecular geometry and is paramagnetic. The name copperas dates from times when the copper(II) sulfate was known as blue copperas, and perhaps in analogy, iron(II) and zinc sulfate were known respectively as green and white copperas ...

    A metal ion in aqueous solution or aqua ion is a cation, dissolved in water, of chemical formula [M(H 2 O) n] z+.The solvation number, n, determined by a variety of experimental methods is 4 for Li + and Be 2+ and 6 for most elements in periods 3 and 4 of the periodic table.

  5. Single displacement reaction - Wikipedia

    en.wikipedia.org/wiki/Single_displacement_reaction

    When a copper wire is dipped in a silver nitrate solution, copper displaces silver, turning the solution blue and solid silver precipitates out ("silver tree"): Cu + AgNO₃ → Cu(NO₃)₂ + Ag↓ NCSSM video on single displacement reaction Formation of tin crystals as zinc displaces tin, seen under microscope.

  6. Fenton's reagent - Wikipedia

    en.wikipedia.org/wiki/Fenton's_reagent

    The free radicals generated by this process engage in secondary reactions. For example, the hydroxyl is a powerful, non-selective oxidant. [6] Oxidation of an organic compound by Fenton's reagent is rapid and exothermic and results in the oxidation of contaminants to primarily carbon dioxide and water.

  7. Copper sulfide - Wikipedia

    en.wikipedia.org/wiki/Copper_sulfide

    Prominent copper sulfide minerals include Cu 2 S and CuS . In the mining industry, the minerals bornite or chalcopyrite, which consist of mixed copper-iron sulfides, are often referred to as "copper sulfides". In chemistry, a "binary copper sulfide" is any binary chemical compound of the elements copper and sulfur.

  8. List of copper salts - Wikipedia

    en.wikipedia.org/wiki/List_of_copper_salts

    Copper is a chemical element with the symbol Cu (from Latin: cuprum) and the atomic number of 29. It is easily recognisable, due to its distinct red-orange color.Copper also has a range of different organic and inorganic salts, having varying oxidation states ranging from (0,I) to (III).

  9. Spectator ion - Wikipedia

    en.wikipedia.org/wiki/Spectator_ion

    A spectator ion is an ion that exists both as a reactant and a product in a chemical equation of an aqueous solution. [1] For example, in the reaction of aqueous solutions of sodium carbonate and copper(II) sulfate: 2 Na + + CO 2− 3 (aq) + Cu 2+ (aq) + SO 2− 4 (aq) → 2 Na + (aq) + SO 2− 4 (aq) + CuCO 3
