Hydrated copper(II) phosphate precipitates upon addition of a solution of alkali metal phosphate to an aqueous solution of copper(II) sulfate. [4] The anhydrous material can be produced by a high-temperature (1000 °C) reaction between diammonium phosphate and copper(II) oxide. [5] 2 (NH 4) 2 HPO 4 + 3 CuO → Cu 3 (PO 4) 2 + 3 H 2 O + 4 NH 3

Copper(II) sulfate is an inorganic compound with the chemical formula Cu SO 4. It forms hydrates CuSO 4 · n H 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 ]
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Copper phosphate may refer to : Copper(II) phosphate, cupric salt of phosphoric acid; Copper(I) phosphate, cuprous salt of phosphoric acid; A number of copper phosphate minerals, including : Turquoise, a hydrated basic copper aluminium phosphate, CuAl 6 (PO 4) 4 (OH) 8 ·4H 2 O; Pseudomalachite, a basic copper phosphate similar in appearance to ...
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).
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 Bordeaux mixture. [3] Ball-and-stick model of the complex [Cu(NH 3) 4 (H 2 O) 2 ...
Copper phosphide can be produced in a reverberatory furnace or in a crucible, e.g. by a reaction of red phosphorus with a copper-rich material. It can also be prepared photochemically, by irradiating cupric hypophosphite with ultraviolet radiation. [5] It can also be produced by reducing copper(II) phosphate with aluminum. [6]
