The element with the greater reduction potential is the one that is reduced.
The element with the greater reduction potential is the one that is reduced.
The reduction potential plus oxidation potential is negative.
Which element will be oxidized and which will be reduced
In an electrolytic cell, an external power source is needed to drive a non-spontaneous redox reaction, while in a voltaic cell, the redox reaction is spontaneous and generates electric energy. In an electrolytic cell, the anode is positive and the cathode is negative, whereas in a voltaic cell, the anode is negative and the cathode is positive.
The element with the greater reduction potential is the one that is reduced.
The element with the greater reduction potential is the one that is reduced.
Which element will be oxidized and which will be reduced
spontaneous redox reaction
For a redox reaction to be spontaneous, the standard cell potential (cell) must be positive.
A redox reaction can be identified by the transfer of electrons between reactants. Look for changes in oxidation states of elements involved in the reaction to determine if it is a redox reaction.
. The reaction will be spontaneous.
A positive sum of the two half-reactions' standard potentials
oxidation
Which element will be oxidized and which will be reduced
The sum of the voltages of the half-reactions is positive.
The element with the greater reduction potential is the one that is reduced.
