Interpretation:
The difference between electrolytic cell and galvanic cell should be explained.
Concept Introduction:
The oxidation and reduction can be identified by change in oxidation state. If oxidation state of atom of an element increases, it undergoes oxidation and if it decreases, it undergoes reduction.

- . In which direction do electrons flow in a galvanic cell, from anode to cathode or vice versa?arrow_forwardThe mass of three different metal electrodes, each from a different galvanic cell, were determined before and after the current generated by the oxidation-reduction reaction in each cell was allowed to flow for a few minutes. The first metal electrode, given the label A, was found to have increased in mass; the second metal electrode, given the label B, did not change in mass; and the third metal electrode, given the label C, was found to have lost mass. Make an educated guess as to which electrodes were active and which were inert electrodes, and which were anode(s) and which were the cathode(s).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
