CHEMISTRY LABORATORY ELECTROPLATING I.
Reagent needed/Glassware 1) CuSO4 2) Beaker 3) Graduated cylinder 4) Stirring Rod
II.
Procedure 1) Measure sufficient amount of CuSO4 in a beaker. 2) Dissolve CuSO4 in 250ml H2O. 3) Stir the solution until the CuSO4 is dissolved. 4) Place the object in CuSO4 sol’n.
III. 1.What are the possible reaction? ANODE: Cu+HSO4ˉ+H2O ———►
CuSO4+H3Oˉ+2eˉ
CATHODE: CuSO4+H3Oˉ+2eˉ ———►
Cu+HSO4ˉ+H2O
2.What is the amount in grams of cuSO4 in preparing one molar Cu Sol’n? Show How you derive the amount of CuSO4 to be dissolved in 250ml. H2O. 1mole x 250ml x 1L 1L 1000ml 0.25mole x 159.54gCuSO4 1mole
