In the presence of water or moist air at 25 °C, CuCO 3 is stable only for p CO 2 above 4.57 atmospheres and pH between about 4 and 8. [8] Below that partial pressure, it reacts with water to form a basic carbonate (azurite, Cu 3 (CO 3) 2 (OH) 2). [3] 3 CuCO 3 + H 2 O → Cu 3 (CO 3) 2 (OH) 2 + CO 2. In highly basic solutions, the complex anion ...
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.
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/(100 mL)), unless shown otherwise. The substances are listed in alphabetical order.
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.
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).
The result: 1 liter of water can dissolve 1.34 × 10 −5 moles of AgCl at room temperature. Compared with other salts, AgCl is poorly soluble in water. For instance, table salt (NaCl) has a much higher K sp = 36 and is, therefore, more soluble. The following table gives an overview of solubility rules for various ionic compounds.
