Question
  1. What would the voltmeter read if metal A were connected to the red lead, with metal C being connected to black?
Consider the following activity series of metals: Sn2* (ag) + 2e-→ Sn (s) Pb2* (ag) + 2e-> Pb (s) Fe2+ (ag) + 2e-→ Fe (s) Al3+ (aq) + 3e- → Al (s) -0.14 V -0.13 V -0.44 V -1.66 V In a setup identical to that described in the laboratory procedure, the four metals are arranged as A-D, with each one surrounded by a solution containing the cation (for example, SnCl2 (ag) with Sn, etc.). Metal A is Al, with B, C, and D being Sn, Fe and Pb, respectively. For each, the black lead of the voltmeter is connected to Metal A. 1. What would be the observed voltages for each combination? Complete the table below. Metal (black) Metal (red) Voltage OV A A 0.01V A C 0.30V D 1.52V B.
