The nature of the resulting copper(II) hydroxide however is sensitive to detailed conditions. Some methods produce granular, robust copper(II) hydroxide while other methods produce a thermally sensitive colloid-like product. [3] Traditionally a solution of a soluble copper(II) salt, such as copper(II) sulfate (CuSO 4 ·5H 2 O) is treated with ...

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.
Basic copper carbonate is a chemical compound, more properly called copper(II) carbonate hydroxide. It can be classified as a coordination polymer or a salt. It consists of copper(II) bonded to carbonate and hydroxide with formula Cu 2 (CO 3)(OH) 2. It is a green solid that occurs in nature as the mineral malachite.
Copper(I) bromide: 7.38 (18–20 °C) Copper(I) chloride: 5.99 (18–20 °C) Copper(II) iodate: 6.85 Copper(I) iodide: 11.30 (18–20 °C) Copper(II) oxalate: 7.54 Copper(I) thiocyanate: 10.80 (18 °C) Iron(II) hydroxide: 13.79 (18 °C) Iron(III) hydroxide: 35.96 (18 °C) Lead(II) carbonate: 13.48 (18 °C) Lead(II) fluoride: 7.43 (26.6 °C ...
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).
It can be formed by heating copper in air at around 300–800 °C: 2 Cu + O 2 → 2 CuO. For laboratory uses, copper(II) oxide is conveniently prepared by pyrolysis of copper(II) nitrate or basic copper(II) carbonate: [4] 2 Cu(NO 3) 2 → 2 CuO + 4 NO 2 + O 2 (180°C) Cu 2 (OH) 2 CO 3 → 2 CuO + CO 2 + H 2 O. Dehydration of cupric hydroxide ...
3, such as mixing solutions of copper(II) sulfate CuSO 4 and sodium carbonate in ambient conditions, yield instead a basic carbonate and CO 2, due to the great affinity of the Cu 2+ ion for the hydroxide anion HO −. [5] Thermal decomposition of the basic carbonate at atmospheric pressure yields copper(II) oxide rather than the carbonate.
