In a galvanic cell, one half-cell consists of a lead strip dipped into a 1.00 M solution of Pb(NO3)2. In the second half-cell, solid uranium is in contact with a 1.00 M solution of U(NO3)3. Pb is observed to plate out as the galvanic cell operates, and the initial cell voltage is measured to be 1.672 V at 25°C. (a) Write balanced equations for the half-reactions at the anode and the cathode. Show electrons as e-. Use the smallest integer...
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...
