Is Copper II Carbonate Soluble in Water?

is copper ii carbonate soluble in water?

Copper ii carbonate, also known as cupric carbonate or malachite green copper carbonate, is an inorganic compound with the chemical formula Cu2(OH)2CO3. It is analogous to the mineral malachite and is commonly used as a pigment.

It is soluble in cold water and alcohol, and acid soluble to form the corresponding copper salt. It is also soluble in aqueous solutions of cyanide, sodium hydroxide, ammonium salts and alkali metal carbonates to produce copper complexes.

Common Uses:

Copper carbonate is used in the production of flares, fireworks, paint pigments, solid phosphor activators, pesticides, seed treatment and as fungicides and antidotes. It is also used in electroplating, and in the manufacturing of copper compounds.

Toxicity:

Excessive amounts of copper ii carbonate cause gastrointestinal problems, including acute gastroenteritis, with the hydrogen-sulfur reaction playing an important role. Symptoms include vomiting of 0.20.5 g for oral administration and l 2 g for inhalation, accompanied by nervous system dysfunction, liver and kidney dysfunction, nasal septum ulcer and perforation, facial skin, hair and conjunctiva turn light yellow-green or light black-green, and dust or solution may irritate the eyes and mucous membranes.

Chronic poisoning develops in the long term. In a study on six large white pigs fed on maize meal diets with 600 ppm basic cupric carbonate for 48 days, the animals showed gradual depletion of body weight gain, depression in serum GOT, GPT and LDH activities, and loss of hepatic and renal function. In addition, the pigs in the fish-meal group showed significant signs of toxicity.

Silver Carbonate – What Is It?

Silver Carbonate: What Is It?

It is a transition metal carbonate with the formula Ag2CO3 and is widely used as a chemical intermediate in organic reactions. It is also used in the manufacturing of fireworks and as a pigment for photography.

Silver Carbonate Can Be Precipitated From Sodium Carbonate

When you combine silver nitrate with another of the transition metal carbonates, it will precipitate out and you can use it as an oxidant in the Fetizon reaction.

Fetizon’s Reagent is Made With Silver Carbonate And Celite

When Fetizon combines silver carbonate with an alkaline carbonate, such as celite, a white mass forms that, when washed, turns yellow as the soluble salts separate. This reagent is used to oxidise primary and secondary alcohols, yielding ketones and aldehydes, respectively.

General Reactions With Silver Carbonate

A wide range of organic transformations involving Ag2CO3 have been reported, including carboxylations, halogenations, C-H bond functionalizations, and cycloadditions. For example, Zou and co-workers reported a direct C(sp2)-H phosphorylation of indoles in the presence of Mg(NO3)2 leading to phosphoindoles (Scheme 45) [62].

A number of other organic transformations have been catalyzed by Ag2CO3 in recent years, including C-C/N-H oxidative cross-coupling and cyclization reactions, which produce useful intermediates such as furans and pyrroles. Additionally, Ag2CO3 is frequently used in palladium-catalyzed C-H activations in organic solvents with acidic protons, as an oxidant for single-electron transfer (SET) processes, and as an inorganic base for Wittig reactions. These reactions offer valuable synthetic routes to access potentially bioactive phosphorus-containing heterocycles.

Calcium Carbonate Pellets

Calcium carbonate is an industrial mineral with a wide variety of applications. It is an important component of many aqueous solutions, and is often used as a food additive. It is also a sorbent, anticaking agent and an inhibitor of algal blooms.

In its natural form, calcium carbonate is a polymorphic rock and can be crystallized from aqueous solutions of calcium chloride (CaCl2) and ammonium carbonate (NH4CO3). Calcite is the major product, and aragonite is a minor one.

The chemical composition of aqueous solutions of calcite and aragonite is similar. But calcite crystallizes as a dihydrate, while aragonite is a hexahydrate. In the laboratory, calcite can be produced by placing an aqueous solution of CaCl2 in a desiccator along with ammonium carbonate, and allowing carbon dioxide to diffuse into the aqueous solution.

Pellets can be a valuable addition to a sewage treatment plant, especially for those with a limited space and a high capacity. They have a good density, a very low water absorption coefficient when crushed and high mechanical resistance.

During pelleting, the moisture content of the raw material (MC) has an effect on the density, strength and durability of the pellets. This is why it is essential to choose the right raw materials for a pelleting process. MC should be around 8-12% to prevent the high frictional forces in the compression area from being too great and to ensure the best pellet quality.
