Question

Consider the following galvanic cell:

 

 

E° (V)

Sn4+  +  2 e   →   Sn2+

0.139

Ag+  +  e   →   Ag(s)

0.799

Silver is being _____________ the silver electrode.


  1. deposited on
  2. neither deposited on nor removed from
  3. removed from
This diagram illustrates a galvanic cell setup, featuring two half-cells connected by a salt bridge. 

**Left Half-Cell:**
- **Electrode:** Tin (Sn)
- **Solution:** Contains tin ions, specifically \(\text{Sn}^{2+}\) and \(\text{Sn}^{4+}\).

**Right Half-Cell:**
- **Electrode:** Silver (Ag)
- **Solution:** Contains silver ions, specifically \(\text{Ag}^+\).

**Salt Bridge:**
- The salt bridge contains potassium chloride (KCl), allowing the flow of ions to maintain electrical neutrality.

**Overall Cell:**
- The circuit is closed with an external wire connecting the two electrodes, allowing for electron flow. The galvanic cell generates electrical energy from spontaneous redox reactions occurring between the tin and silver ions. 

This setup is often used to demonstrate the principles of electrochemistry and energy conversion in a classroom or laboratory setting.
