### Voltaic Cell Description and Analysis #### Diagram Explanation The image displays a schematic representation of a voltaic cell with the following components: - **Voltmeter**: Measures the electrical potential difference between the electrodes. - **Switch**: Controls the flow of electrons in the circuit. - **KNO₃ Salt Bridge**: Maintains electrical neutrality by allowing the flow of ions between the two half-cells. - **Cu (Copper) Electrode**: Placed in a 1.0 M Cu(NO₃)₂ solution. - **Sn (Tin) Electrode**: Placed in a 1.0 M Sn(NO₃)₂ solution. The setup demonstrates a typical galvanic cell, where redox reactions occur, and electron flow is facilitated from one metal electrode to the other. #### Questions and Analysis 2) The voltaic cell pictured above is constructed with electrodes of known mass. The switch is closed and the cell is allowed to operate for a period of time. At that point, the electrodes were rinsed, dried, and massed and it was discovered that the copper metal had a higher mass than it initially had. a) **Which metal is the anode?** - The anode is the metal where oxidation occurs. In this cell, tin (Sn) acts as the anode. b) **Which metal is the cathode?** - The cathode is where reduction takes place. In this cell, copper (Cu) is the cathode. c) **Write the half equation for the process that occurs at the anode.** - \( \text{Sn (s)} \rightarrow \text{Sn}^{2+} + 2e^- \) d) **Write the half equation for the process that occurs at the cathode.** - \( \text{Cu}^{2+} + 2e^- \rightarrow \text{Cu (s)} \) e) **Write the overall equation for the reaction.** - \( \text{Sn (s)} + \text{Cu}^{2+} \rightarrow \text{Sn}^{2+} + \text{Cu (s)} \) f) **Will electrons flow from the copper electrode to the tin electrode or from the tin to the copper?** - Electrons will flow from the tin electrode (anode) to the copper electrode (cathode). g) **
