Concentration Cell: Direction of Electron Flow, Nernst Equation

WebThe two half-cells in a galvanic cell are the cathode and anode. The cathode is the half-cell which is receiving electrons. For us, it's the copper half-cell. The anode is the half-cell which is giving electrons. For us, it's the zinc half-cell. It's also important to note that there is a salt bridge which allows ions to flow to the two half-cells. WebConcentration cell: A galvanic cell in which the two half-cells are the same except for the concentration of the solutes; spontaneous when the overall reaction is the dilution of the solute.
