Question

Select the true statement about oxidation and reduction in an electrolytic cell. a) both oxidation and reduction occur at the anode. b) both oxidation and reduction occur at the cathode. c) oxidation occurs at the anode and reduction occurs at the cathode. d) oxidation occurs at the cathode and reduction occurs at the anode.

Lamar Hirthe · Accepted Answer

C) Oxidation occurs at the anode and reduction occurs at the cathode.

Lamar Hirthe · Answer

C) Oxidation occurs at the anode and reduction occurs at the cathode.Explanation:Electrolytic cells are a form of electrochemical cells in which a non-spontaneous redox reaction is driven by the application of electrical energy. Here electrical energy is converted to chemical energy. These are composed of two half cells; a positively charged anode where oxidation takes place and a negatively charged cathode where reduction takes place. The two electrodes are placed in the same container that holds the molten electrolyte. For example, the decomposition of salt (NaCl) is carried out in an electrolytic cell. The overall reaction is:At cathode: ReductionNa^{+} + e- rightleftharpoons Na(s)At anode: oxidation2Cl^{-}+ 2e-rightleftharpoons Cl_{2}(g)

a substance cannot gain electron without taking them out from another substance.Hope this helps

Lamar Hirthe · Answer

C. Oxidation occurs at the anode and reduction occurs at the cathode.Choice number third is the correct option for the given questionExplanation: Copper and silver nitrate are the two components that form a voltaic cell. These are the two main ingredients which make the Redox reaction possible. The dog reaction that is taking place result in development of charge. Since copper here is the anode in the reaction oxidation happens here by the solution is cathode this is where reduction takes place.

Lamar Hirthe · Answer

I believe the correct answer would be that oxidation occurs at the anode and reduction occurs at the cathode. A voltaic cell uses chemical reaction in order to produce electrical energy. It is in the anode that the oxidation reaction happens while in the cathode reduction happens.

Lamar Hirthe · Answer

It's C

Lamar Hirthe · Answer

Oxidation is the loss of electrons and corresponds to an increase in oxidation state. A reduction is the gain of electrons and corresponds to a decrease in oxidation state. Balancing redox reactions can be more complicated than balancing other types of reactions because both the mass and charge must be balanced. Redox reactions occurring in aqueous solutions can be balanced by using a special procedure called the half-reaction method of balancing. In this procedure, the overall equation is broken down into two half-reactions: one for oxidation and the other for reduction. The half-reactions are balanced individually and then added together so that the number of electrons generated in the oxidation half-reaction is the same as the number of electrons consumed in the reduction half-reaction.

Lamar Hirthe · Answer

The answer is A. Voltaic cells couple oxidation and reduction half reactions to produce electromotive force from chemical potential energy. Electrolytic cells do the opposite in that they require electromotive force to store chemical energy.
