Chem 1212 Lab Report on electrochemistry Electrochemistry When electrons transfer between reaction components in a redox reaction, we can harness the motion of the electrons to create a potential. Electrochemistry revolves around the separation of the two half-reactions in a redox reaction and establishing two different electrodes. This might involve physically separating the half-reactions or including a separator, such as a semi-permeable membrane or plastic dividers. With the reactions separated, the electrons will need to flow through the wire connecting...

Draw out a cell for Al in Al(NO3)3 and Ag in AgNO3. Label the anode and cathode sides, including charge on each electrode. (hint: use a table of standard reduction potentials). Indicate direction of electron flow. Write the net reaction, and the half reactions. What is the standard cell potential? Indicate for both electrodes whether they are dissolving, growing, or staying the same size. Assuming the salt bridge contains KNO3, indicate flow of ions into and out of salt bridge....
