Where does reduction occur in an electrochemical cell?
Answer
Reduction occurs at the cathode, and oxidation occurs at the anode. (Note: Reduction and cathode both start with a consonant; and oxidation and anode both start with a vowel).
If a cell is constructed from a tin half-cell and a silver half cell, which statement is true? (The half-cell potential for the silver half-cell is 0.80V, and the half-cell potential for the tin half-cell is -0.14V.)
Since Ag+ has a more positive reduction potential, Ag+(aq) will be reduced to Ag(s). The tin reaction is reversed, and Sn(s) will be oxidized to Sn2+(aq).
