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.
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 ·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]
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. The reaction of copper metal with naphthenic acid, which has been used commercially, requires ...
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).
In aqueous solution, copper(II) exists as [Cu(H 2 O) 6] 2+. This complex exhibits the fastest water exchange rate (speed of water ligands attaching and detaching) for any transition metal aquo complex. Adding aqueous sodium hydroxide causes the precipitation of light blue solid copper(II) hydroxide. A simplified equation is:
Sodium phosphate; see trisodium phosphate – Na 3 PO 4; Sodium selenate – Na 2 O 4 Se; Sodium selenide – Na 2 Se; Sodium selenite – Na 2 SeO 3; Sodium silicate – Na 2 SiO 3; Sodium sulfate – Na 2 SO 4; Sodium sulfide – Na 2 S; Sodium sulfite – Na 2 SO 3; Sodium tartrate – C 4 H 4 Na 2 O 6; Sodium tellurite – Na 2 TeO 3 ...
