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.
What else can I help you with?
What do negative oxidation mean?
Negative oxidation typically refers to reduction, which is the gain of electrons or a decrease in oxidation state of a molecule. In this process, a molecule or atom undergoes a reduction reaction by accepting electrons.
What chemical process must always accompany a reduction process?
Oxidation is the chemical process that must always accompany a reduction process, as they occur simultaneously in a redox reaction where electrons are exchanged between reactants.
How do you determine if a reaction is an oxidation-reduction reaction?
An oxidation-reduction reaction can be determined by looking for changes in the oxidation states of the elements involved. If an element loses electrons (oxidation) and another gains electrons (reduction), it is likely an oxidation-reduction reaction.
Can oxidation be reversed in any way?
Yes, oxidation can be reversed through a process called reduction, where electrons are gained by the oxidized substance.
What is it called when chlorine becomes chloride?
When chlorine becomes chloride, the chlorine gains an electron to form an anion. This process is called oxidation. Oxidation always occurs with reduction (loss of an electron from another substance) in an oxidation reduction reaction.
What is reduction process?
A reduction process involves the gain of electrons by a substance, resulting in a decrease in oxidation state. It is the opposite of oxidation and is essential in many chemical reactions, such as in redox reactions. Reduction reactions often occur simultaneously with oxidation reactions to maintain charge balance.
What one is chemical property oxidation reduction electrolysis all are correct?
Oxidation and reduction are chemical properties. Electrolysis is a chemical process, not a property.
Is it possible to have a reaction in which oxidation takes place but reduction does not?
Oxidation is characterized by the loss of electrons, and reduction is characterized by the gain of electrons. Since there must be an electron loser and an electron receiver, oxidation and reduction are always complimentary.
What do negative oxidation mean?
Negative oxidation typically refers to reduction, which is the gain of electrons or a decrease in oxidation state of a molecule. In this process, a molecule or atom undergoes a reduction reaction by accepting electrons.
Why photosynthesis is called oxidation reduction process?
Photosynthesis is called an oxidation-reduction process because it involves the reduction of carbon dioxide to glucose (an energy-rich molecule) coupled with the oxidation of water to produce oxygen. During this process, electrons are transferred from water to carbon dioxide, resulting in a redox reaction that is essential for creating energy for the plant.
Why is NO3 to NO a reduction?
In the reaction where NO₃^- is reduced to NO, nitrogen changes from a higher oxidation state (+5 in NO₃^-) to a lower oxidation state (+2 in NO). This reduction process involves gaining electrons and therefore is considered a reduction reaction.
What element is used in the reduction process?
In the reduction process, electrons are typically used to reduce an element by gaining or accepting the electrons. The element being reduced gains electrons, thereby decreasing its oxidation state.
What chemical process must always accompany a reduction process?
Oxidation is the chemical process that must always accompany a reduction process, as they occur simultaneously in a redox reaction where electrons are exchanged between reactants.
Is reduction physical or chemical?
Reduction can involve both physical and chemical changes. In a chemical sense, reduction involves gaining electrons to form a lower oxidation state. In a physical sense, reduction can refer to the process of decreasing the size or amount of a substance.
How do you determine if a reaction is an oxidation-reduction reaction?
An oxidation-reduction reaction can be determined by looking for changes in the oxidation states of the elements involved. If an element loses electrons (oxidation) and another gains electrons (reduction), it is likely an oxidation-reduction reaction.
What is fermentation the opposite of?
There is no opposite or reverse reaction, but fermentation is an anaerobic process, one not requiring oxygen. The aerobic equivalent would be respiration (oxidation).
Can oxidation be reversed in any way?
Yes, oxidation can be reversed through a process called reduction, where electrons are gained by the oxidized substance.
