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 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.

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 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]
Sales rose this year during the holiday shopping season even as Americans wrestled with elevated prices for many groceries and other necessities, according to new data. Holiday sales from the ...
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.
Seven people, including one American citizen, were hospitalized over the weekend for suspected poisoning after drinking cocktails at a hotel resort bar in Fiji, health officials said Monday.
