Question

Using your knowledge of the concepts from the lab procedure, identify the labeled components of "CuPb" voltaic cell below (+) 1. Positive terminal of voltage probe 2. Negative terminal of voltage probe 3. Lead nitrate, P u la 4. Potassium nitrate KNO3 sat bridge 5. Calcium nitrate. Ca Nostal 6. Lead P electrode 7. Copper nitrate NO2 Copper ulectrode

Answer 1

Answer 1 - A = Positive terminal of voltage probe B = Negative terminal of voltage probe. - Copper (cu) electrode Da Lead (Pb) electrode. E Potassium nitrate (KNO₂) salt bridge. to Copper nitrate cuCNO₃)2 caq. G = Lead nitrate Pb(NO3)2 cago. - As lead is more reachine in the galvanic series as compared to copper Hence, lead is kept on anode side. pre negative terminal voltage probe.. And Copper is kept on cathode side le positive terminal voltage probe The half cell reactions are salt bridge. Anode half cellly cathode half cell I Pbcs) / Pbt caq oth caq | Cuis). - Electron flow . - At anode metal loses electrone means oxidation occurs and at cathode metal gains electrons means reduction occur. the flow of electrons is from anode to Cathode withia salt bridge CamScanner
