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...

In which direction do the ammonium ions move when this salt bridge completed the electric circuit? Toward the zinc metal or toward the copper metal? In which direction do the nitrate ions move? 2. In a concentration cell, what would be the potential if we studied two solutions that had the same concentration? Show that the...
