Galvanic Cell Changes: Copper Deposition on X

Click For Summary
SUMMARY

During the electrolysis process described, 1.05 g of copper is deposited on electrode X, leading to the conclusion that 3.60 g of silver is lost from electrode W. The calculation indicates that 0.01667 mol of copper corresponds to 0.0333 mol of electrons transferred, resulting in a proportional loss of silver at the anode. The discussion also identifies option C, which states that Z is a salt bridge, as a potential correct answer, although the user mistakenly identifies Z as a wire.

  1. A) The mass of silver electrode W decreases by 3.60 g.
  2. B) The mass of silver deposited on electrode Y during the electrolysis is 1.80 g.
  3. C) Z is a salt-bridge.
  4. D) The concentration of copper ions in solution decreases during the electrolysis.
  5. E) The flow of negative charge is from right to left in Z.

Homework Equations

The Attempt at a Solution



I chose A. Since 1.05g of Cu is deposited, there are 0.01667 mol of Cu deposited. This means there are 0.0333 mol of electrons transferred. Which means there are 0.0333 mol of Ag lost in the anode. This means the anode lost 3.60g of Ag. However, C also makes sense as Z is the salt bridge. Could someone tell me where I went wrong?
