Concept Introduction:
Oxidation is the addition of an electronegative element or the removal of an electropositive element in a
Reduction is the addition of an electropositive element or the removal of an electronegative element in a chemical reaction.
The chemical reaction in which oxidation process and reduction process take place simultaneously, is called a redox reaction.
An electrochemical cell is also known as a galvanic or voltaic cell.
The electrochemical cell is a type of battery that converts chemical energy into electrical energy.

- As an example of an electrolytic cell, the text states: Sodium chloride is electrolyzed commercially in an apparatus called the Downs cell to produce sodium and chlorine. This is a high-temperature operation; the electrolyte is molten NaCl. Write the half-reaction equations for the changes taking place at each electrode. Is the electrode at which sodium is produced the anode or the cathode? The Downs cell electrolyzes molten melted sodium chloride, producing sodium and chlorine.arrow_forward. In which direction do electrons flow in a galvanic cell, from anode to cathode or vice versa?arrow_forwardGive the notation for a voltaic cell whose overall cell reaction is Mg(s)+2Ag+(aq)Mg2+(aq)+2Ag(s) What are the half-cell reactions? Label them as anode or cathode reactions. What is the standard cell potential of this cell?arrow_forward
