No, oxidation cannot occur without reduction occurring at the same time. This is the case since gaining electrons means another element losing due to the fact that electrons cannot be destroyed.

∙ 13y agoOxidation is loosing electrones. E.g. an anode in a battery. The electrons lost have to reduce something, they need to end somewhere, e.g. a cathode. However by way of philosophical thinking you may send them to ground (by way of current rectifier) which is an infinite drain for electrons and assume no reduction

∙ 13y agoGenerally, no. However, in electrochemical reactions driven by an externally imposed electromotive force and having a partial migration barrier between the two electrodes, it is possible to separate the oxidation and reduction reactions from one another in different compartments in space, with charge neutrality in each compartment being maintained by diffusion of some other charged entity not directly involved in the reaction.

∙ 12y agoSuch substance is called an OXIDIZING AGENT. It oxidizes another substance it reacts with by displacing the Hydrogen atom present in the substance thereby gaining it and becoming REDUCED while it donates OXYGEN to the other substance,OXIDIZING it.

∙ 9y agoYes, it is possible. Previous definitions of oxidationmeant a "reaction with oxygen". However, over time the definition became more generalized and meant the loss of electrons by substance, or an increase in the valence state/number of a substance. So for example, there is no oxygen present in the reaction of aluminum, but it is considered to be an oxidation reaction:
Al(metal) + 3 H2O + OH (-1) = (A[OH]4)(-1) + 3/2 H2

Which balanced equation represents an oxidation-reduction reaction?
Equations that separate the oxidation from the reduction parts of the reaction
Does Oxidation and reduction reactions occur at the same time?
Yes, an element can undergo both oxidation and reduction in the same reaction. The reaction between Zinc and Copper Sulphate is a perfect example. This type of reaction is called a redox reaction.
Why is oxidation and reduction processes are complementary?
Oxidation is loss of electrons. Reduction is gain of electrons.Therefore in a redox reaction one substance will lose electrons which the other picks up and gains.So the complimentary part is because in order for one substance to gain electrons another in the system must be losing them.I think that is what is meant - although it has been many years indeed!-from von2 posadas of EN 4A UE Caloocan
Undergo no chemical change during a chemical reaction?
A catalyst doesn't undergo a chemical change during a chemical reaction.
Why a substance that speeds up a chemical reaction without being permanently changed itself?
A Catalyst.From wikipedia: "Catalysis is the process in which the rate of a chemical reaction is increased by means of a chemical substance known as a catalyst. Unlike other reagents that participate in the chemical reaction, a catalyst is not consumed by the reaction itself. The catalyst may participate in multiple chemical transformations."http://en.wikipedia.org/wiki/Catalyst
What reaction is reduction?
In chemistry, reduction is considered the gaining of electrons. Oxidation is the lose of electrons. They go together in reactions called redox (reduction/oxidation). You cannot have a reduction without also having an oxidation.

Equations that separate the oxidation from the reduction parts of the reaction
How the processes of oxidation and reduction related?
In a reaction where one reactant is being oxidised another reactant is necessarily being reduced. Reduction cannot occur without oxidation, and vice versa.
Does Oxidation and reduction reactions occur at the same time?
Yes, an element can undergo both oxidation and reduction in the same reaction. The reaction between Zinc and Copper Sulphate is a perfect example. This type of reaction is called a redox reaction.
The following reaction takes place in an acidic solution. MnO4–(aq) + Cl–(aq) Mn2+ + Cl2(g) (unbalanced) Write the reduction and oxidation half-reactions (without electrons). :(?
Reduction Half-Reaction: MnO4-(aq) → Mn2+(aq) Oxidation Half-Reaction: Cl-(aq) → Cl2(g)
Oxidation cannot occur without?
reduction
Is it possible for oxidation to occur without reduction?
o it s not possible
Why does a reduction reactions always accompany an oxidation reaction?
Redox. You can't have the re without the dox, or is that ox without the red? You can't throw away electrons, nor will electrons pop out of thin air.Oxidation is the loss of electrons, reduction is the gain of electrons. In order for one atom to lose electrons another atom must gain them. Hence, reduction must be accompanied by oxidation and vice versa.

Why must oxidation and reduction occur simultaneously?
Because for oxidation to take place the electrons lost by the substance that is oxidized must be accepted by atoms or ions of another substance. Also, for reduction to occur the electrons gained by the substance that is being reduced must be transferred from the atoms of ions of another substance. Therefore, oxidation and reduction are complementary processes: that is to say that oxidation cannot occur without reduction and visa versus.
Which best identifies why the rusting of an iron nail in the presence of water and oxygen is an oxidation-reduction reaction?
Evidence of a chemical reaction from the rusting of an iron nail is the formation of brown Iron Oxide. The oxidation of iron is a chemical reaction.Rust is iron oxide. The presence of rust indicates that the iron in the nail has oxidized, which is a chemical reaction.
Is fermentation an oxidation or a reduction process?
Fermentation is not considered as an oxydation reaction. ------------------------------------------------------------------ It may not usually be considered as such, but the oxidation state of C in sugar is zero, and the oxidation state of C in ethanol is -2. Any change in oxidation state can be treated as a redox process. Loss of electrons (or an increase of oxidation state) is oxidation, gain of electrons (or a decrease of oxidation state) is reduction. The carbon that ends up in the ethanol has decreased its oxidation state from 0 to -2 so those atoms have undergone reduction. Reduction cannot exist without a subsequent oxidation, so something else has undergone oxidation. The fermentation process also makes carbon dioxide. The C in those molecules has an oxidation state of +4, so those atoms of carbon have been oxidized. So the answer is --- both.
