Copper(II) sulfate is an inorganic compound with the chemical formula Cu SO 4.It forms hydrates CuSO 4 ·nH 2 O, 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]
Magnesium sulfate or magnesium sulphate is a chemical compound, a salt with the formula MgSO 4, consisting of magnesium cations Mg 2+ (20.19% by mass) and sulfate anions SO 2− 4. It is a white crystalline solid , soluble in water but not in ethanol .
"It can also be prepared by electrolysis of magnesium sulfate [Epsom salts] solution at moderate voltage with a copper anode: this reaction produces hydrogen, copper sulfate solution, and copper hydroxide precipitate." what happens to the magnesium? MgSO4(aq) + Cu(S) --dc--> h2(g) + Mg(OH)2(s) + CuSO4(aq) would make more sense.
Magnesium hydride was first prepared in 1951 by the reaction between hydrogen and magnesium under high temperature, pressure and magnesium iodide as a catalyst. [1] It reacts with water to release hydrogen gas; it decomposes at 287 °C, 1 bar: [2] MgH 2 → Mg + H 2. Magnesium can form compounds with the chemical formula MgX 2 (X=F
Consider the Galvanic cell shown in the adjacent image: it is constructed with a piece of zinc (Zn) submerged in a solution of zinc sulfate (ZnSO 4) and a piece of copper (Cu) submerged in a solution of copper(II) sulfate (CuSO 4). The overall reaction is:
Magnesium borate, magnesium salicylate, and magnesium sulfate are used as antiseptics. Magnesium bromide is used as a mild sedative (this action is due to the bromide , not the magnesium). Magnesium stearate is a slightly flammable white powder with lubricating properties.
For many substances, the formation reaction may be considered as the sum of a number of simpler reactions, either real or fictitious. The enthalpy of reaction can then be analyzed by applying Hess' law, which states that the sum of the enthalpy changes for a number of individual reaction steps equals the enthalpy change of the overall reaction.
A spectator ion is an ion that exists both as a reactant and a product in a chemical equation of an aqueous solution. [1] For example, in the reaction of aqueous solutions of sodium carbonate and copper(II) sulfate: 2 Na + + CO 2− 3 (aq) + Cu 2+ (aq) + SO 2− 4 (aq) → 2 Na + (aq) + SO 2− 4 (aq) + CuCO 3
