Basic copper carbonate is prepared by combining aqueous solutions of copper(II) sulfate and sodium carbonate. Basic copper carbonate precipitates from the solution, with release of carbon dioxide CO 2: [7] 2CuSO 4 + 2Na 2 CO 3 + H 2 O → Cu 2 (OH) 2 CO 3 + 2Na 2 SO 4 + CO 2. Basic copper carbonate can also be prepared by treating aqueous ...
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure.
Benedict's reagent (often called Benedict's qualitative solution or Benedict's solution) is a chemical reagent and complex mixture of sodium carbonate, sodium citrate, and copper(II) sulfate pentahydrate. [1] It is often used in place of Fehling's solution to detect the presence of reducing sugars and other reducing substances. [2]
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.
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.
One of the early formulas consists of glucose, sodium hydroxide, indigo carmine (dye), and water. Another formula consists of indigo carmine, ascorbic acid , sodium bicarbonate, sodium chloride, copper(II) sulfate, sodium hydroxide and water. [17] By doing so, chemical waste and the level of corrosive chemicals is reduced. The amount of solid ...
