At 60°C, about 31.6 g of copper (II) sulfate will dissolve in 100 g of water. This means that about 3.4 g of copper (II) sulfate will not dissolve and will form a saturated solution.
The oxidation number of copper (II) is +2. This means that copper has lost two electrons in a chemical reaction and has a charge of +2.
B. 24.6 grams. To find this, you must first calculate the molar mass of Cu and CuS. This will give an idea of the mole ratio between Cu and CuS. Then, you can use stoichiometry to determine that 24.6 grams of Cu₂S will yield 10.0 grams of Cu.
No, the addition of extra ammonia will not dissolve Copper II sulfide. Copper II sulfide is insoluble in water and ammonia solution; it does not react with ammonia to form soluble complexes.
The complete ionic equation for the reaction between copper(II) sulfate and barium chloride is: Cu^2+(aq) + SO4^2-(aq) + 2Ba^2+(aq) + 2Cl^-(aq) → BaSO4(s) + CuCl2(aq)
The spectator ions in the reaction between copper (II) chloride (CuCl2) and aqueous ammonium phosphate ((NH4)3PO4) are Cl- and NH4+. These ions do not participate in the chemical reaction and remain unchanged in the solution.
