Copper (II) oxide or cupric oxide is an inorganic compound with the formula CuO. A black solid, it is one of the two stable oxides of copper, the other being Cu 2 O or copper (I) oxide (cuprous oxide). As a mineral, it is known as tenorite, or sometimes black copper. It is a product of copper mining and the precursor to many other copper ...
Copper (II) sulfate is an inorganic compound with the chemical formula Cu SO 4. It forms hydrates CuSO4·nH2O, 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]
Aluminium sulfate is a salt with the formula Al 2 (SO 4) 3. It is soluble in water and is mainly used as a coagulating agent (promoting particle collision by neutralizing charge) in the purification of drinking water [3][4] and wastewater treatment plants, and also in paper manufacturing.
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 solutions of copper(II) sulfate with sodium bicarbonate. Copper(II) sulfate may also be substituted with Copper(II ...
The data below tabulates standard electrode potentials (E °), in volts relative to the standard hydrogen electrode (SHE), at: Absolute partial pressure 101.325 kPa (1.00000 atm; 1.01325 bar) for each gaseous reagent — the convention in most literature data but not the current standard state (100 kPa). Variations from these ideal conditions ...

Copper (I) oxide or cuprous oxide is the inorganic compound with the formula Cu 2 O. It is one of the principal oxides of copper, the other being copper (II) oxide or cupric oxide (CuO).The compound can appear either yellow or red, depending on the size of the particles. [2] Cuprous oxide is found as the mineral cuprite.
Copper. face-centered cubic (fcc) (cF4) Copper is a chemical element; it has symbol Cu (from Latin cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity ...
