The oxidation–reduction reactionCr2O72-(aq) + 14 H+(aq) + 6 I-(aq)--->2 Cr3+(aq) + 3 I2(s) + 7 H2O(l)is spontaneous. A solution containing K2Cr2O7 and H2SO4 is poured into one beaker, and a solution of KI is poured into another.A salt bridge is used to join the beakers. A metallic conductor that will not react with either solution (such as platinum foil) issuspended in each solution, and the two conductors are connected with wires through a voltmeter or some other device to detectan electric current. The resulting voltaic cell generates an electric current. Indicate the reaction occurring at the anode, thereaction at the cathode, the direction of electron migration, the direction of ion migration, and the signs of the electrodes.

Electrolysis

Electrolysis is defined as the process of breaking down ionic compounds into their constituent elements by passing a direct electric current through the compound in a fluid state. The cathode reduces cations, while the anode oxidizes anions. An electrolyte, electrodes, and some form of external power source are the main components required for conducting electrolysis. A partition, such as an ion-exchange membrane or a salt bridge, may also be used, but this is optional. These are primarily used to prevent the products from diffusing near the opposing electrode.
