All of the following statements regarding galvanic cells are TRUE EXCEPT: (A) Electrons flow from the cathode to the anode B Energy is being generated during the process The salt bridge allows movement of ions between the half-cells (D) Oxidation is at the anode and reduction is at the cathode
A common shorthand way to represent a voltaic cell is anode& anode solution& & cathode solution&cathode A double vertical line represents a salt bridge or a porous barrier. A single vertical line represents a change in phase, such as from solid to solution. Using the notation just described, represent a cell based on the following reaction: ClO3 -1aq2 + 3 Cu1s2 + 6 H+1aq2 ¡ Cl -1aq2 + 3 Cu2+1aq2 + 3 H2O1l2 Pt is used as an inert electrode in contact with the ClO3 - and Cl -.
