  • Transformation of Copper A Sequence of Chemical Reactions

    Actually the nitrate ion oxidizes the copper metal to copper (II) ion while itself being transformed to NO 2 gas in the process the copper (II) ion then binds to six water molecules. The physical change you should observe is the copper-colored metal vanishing as the solution turns blue (from Cu(H 2 O) 6 2 the hexaaquacopper ion) and a

  • copper metal from copper ore experiment

    In this experiment copper will be extracted from malachite by reaction with sulfuric acid and then reduced from the acid solution using metallic iron. The reactions for these processes are CuCO3xCu(OH)2 2 H2SO4 → 2 CuSO4 3 H2O CO2

  • Copper Sulfate Lab

    Copper Sulfate absorbs water easily forming a weak bond between the copper sulfate and five water molecules. This is written CuSO4 . 5 H2O. The name of this compound is "copper sulfate pentahydrate". But when copper sulfate is heated (as in a fire) these weak bonds are broken and the water evaporates.

  • Copper sulfate experimental operation precautions

    When weigh the crude copper sulfate crystal we should first grind it in the mortar otherwise it will be difficult and time consuming to weigh and dissolve. 2. Stir with a glass rod to dissolve when heated to dissolve but the glass rod should not touch the wall of the beaker otherwise the beaker will be damaged.
