Passage III
An electrochemical cell (Figure 1) is constructed with an anode, a strip of zinc (Zn) placed in a solution of zinc ions (Zn2+), and a cathode, a strip of copper (Cu) or silver (Ag) placed in a solution of copper ions (Cu2+) or silver ions (Ag1+) , respectively. The solutions are connected by a salt bridge (a tube filled with a solution containing nitrate ions). The anode and cathode are connected to a voltmeter. Tables 1 and 2 show how the mass (g) of the anode or cathode, concentrations (M) of the ionic solutions, and temperature (°C), affect the voltage difference(V) between Zn and either Cu or Ag.
13. Based on the data in Table 1, if an electrochemical cell is constructed with a 5.00 g Zn anode placed in 1.00 M Zn2+ and a 5.00 g Cu cathode placed in 1.00 M Cu2+ at 25°C, what voltage difference is produced?
Your Answer is
Correct Answer is B
Explanation
According to the description in the question stem, it should correspond to Cell 3 in table 1, and the voltage difference is 1100
