Demineralised Water What can be seen when a strip of copper metal is placed in a solution of silver nitrate? Practical activity - identifying the ions in unknown salts. One of the most fascinating chemical experiments is the reaction between silver nitrate and copper wire in water. Fasten the copper foil in the clamp, turn on the power to the conductivity apparatus, and touched the copper to both electrodes of the apparatus simultaneously. The copper is undergoing oxidation; therefore, the copper electrode is the anode. We made observations, recorded them and used our observations to propose a hypothesis. This process is usually accomplished by rinsing the first vessel several times with fresh liquid and pouring each rinse into the receiving vessel. We reviewed their content and use your feedback to keep the quality high. The equation for the reaction of nitric acid with copper is: Cu(s) + 4HNO, The equation for the reaction of copper with silver nitrate solution is: Cu(s) + 2AgNO, Vernier lab interface with temperature probe, Petri dish with a 0.5 cm x 1.0 cm piece of copper foil in it, small bottle of 0.1 M silver nitrate solution, 1 L Florence flask with a stopper containing a 0.5 cm square piece of copper foil. Chemical properties are based on the ability or inability of the substance to produce new substances. When a copper wire is introduced into an aqueous silver nitrate solution, a single replacement reaction occurs. The silver is reduced to elemental silver and the copper is oxidized to copper(II): Cu(0) + 2AgNO 3 = Cu(NO 3) 2 + 2Ag(0) The silver crystallizes at the surface of the copper and the copper wire quickly becomes coated with a bunch of elemental silver. Copper Metal (Cu) + Silver Nitrate (AgNO 3) = Silver Metal (Ag) + Copper Nitrate (CuNO 3) Outcome As the silver nitrate is converted into its elemental form, the deposits of silver coat the surface of the copper wire where they continue to accumulate over time. Silver nitrate is also used as the forerunner in most silver compounds, including those used in photography.
