Can ethanol be converted to acetaldehyde and vise-versa via electrochemistry?

More about the question:
I read on a reduction potential table once:
acetaldehyde + 2H+ + 2e- ----> ethanol
and the potential for this half reaction was -0.163 volts.
I was wondering if this is as simple as stated, or would you need some sort of catalyst? Meaning: Could I just put an electrode (copper wire) into a bottle of ethanol (everclear on hand, 95% in water) and run .2 volts through it to get acetaldehyde? Of course this would be a half cell, and a salt bridge would be needed, right?
The application for this would be as an electrolyte for an organic based flow battery (half of the cell). Would this be feasible?

What is the equation for alcoholic fermentation after glycolysis?
The product of glycolysis is pyruvate. In alcoholic (ethanol) fermentation, pyruvate is converted into ethanol and carbon dioxide. The first step is decarboxylation, catalyzed by pyruvate decarboxylase: CH3COCOO- --> CH3CHO pyruvate --> acetaldehyde Then acetaldehyde is reduced to ethanol; this step is catalyzed by alcohol dehydrogenase and involves the oxidation of NADH+ + H+ to NADH: CH3CHO --> CH3CH2OH
When o2 supply is inadequate pyuvate is converted to?
Pyruvate is converted to ethanol in alcohol fermentation.It is converted to lactic acid in lactic acid fermentation.
What enzyme is used to change glucose into fructose?
In the major pathway of ethanol metabolism the 2 enzymes involved are alcohol dehydrogenase, aldehyde dehydrogenase and thiokinase. ethanol + NAD+ <=> acetaldehyde + NADH + H+ (ethanol dehydrogenase) acetaldehyde + NAD+ <=> acetate + NADH + H+ (aldehyde dehydrogenase) acetate + coA + ATP <=> acetyl coA + AMP + PPi (thiokinase)
Name the two step process where pyruvate is converted to a two carbon compound releasing carbon dioxide. Then the electrons are transferred from a molecule of NADH to the two carbon compound producing?
Pyruvate decarboxylation -> Acetaldehyde reduction The product is ethanol. Pyruvate decarboxylation is performed by pyruvate decarxylase with cofactor thiamine pyrophosphate, and the product, acetaldehyde, is reduced by NADH. (Pyruvate decarboxylase is NOT the same as the pyruvate dehydrogenase complex in cellular respiration. Though pyruvate dehydrogenase also decarboxylates pyruvate, but the decarboxlated species immediately reacts with CoA to form acetyl-CoA).
What is the boiling point of Ethonal?
Ethanol (Ethyl Alcohol) has a melting point of -130 and boils at 78.5. Ethanal (Acetaldehyde) has mp -123.5 0C and bp 20.2 0C
What happens to alcohol when it goes into your blood?
Blood is pumped through the liver where alcohol is metabolized and removed. Ethanol within the human body is converted into acetaldehyde by alcohol dehydrogenase and then into acetic acid by acetaldehyde dehydrogenase. The product of the first step of this breakdown, acetaldehyde, is even more toxic than ethanol.
What does the oxidation of ethanol produce?
Ethanol is first oxidised to acetaldehyde which can be further oxidised to acetic acid
Can ethanol undergo oxidation?
Yes. Under proper conditions, ethanol can be oxidized to ethanal (also called "acetaldehyde"), acetic acid, and/or carbon dioxide.
Does wine have ethanol?
Yes, wine does contain ethanol, wich is acetaldehyde that your body creates after it breaks down the ethanol, processes and leaves the system within the time period of 72 to 80 hours, could take longer depending on how much wine is consume. Apart from the acetaldehyde bull yes. Break down to methanal.

Why ethanol gives haloform reaction?
ethanol gives haloform reaction because it is oxidized to acetaldehyde whose alpha carbon donates a hydrogen atom for the formation of haloform
What is the product of potassium permanganate and acetaldehyde?
what are the major product formed when ethanol reacts with acidified kmno4 solution
What is the reaction between acidified potassium dichromate and ethanol?
ethanol is converted into acetic acid....
Why do you use ethanol in intravenous infusion form to treat methanol intoxication?
The liver metabolizes the ethanol into acetaldehyde in preference to metabolizing the methanol. That slows the buildup of formaldehyde -- with luck, enough to prevent it from building to a lethal level.
What happens when you burn ethanol?
If there is an ample supply of oxygen, the ethanol is converted to carbon dioxide and water.
Why do Asians get drunk faster and sober faster?
A larger percentage of persons of Asian decent, have a dominant gene mutation which interferes with the role of an enzyme called acetaldehyde dehydrogenase. The role of this enzyme is to convert acetaldehyde, a metabolite of ethanol (alcohol), into acetic acid. Persons with this mutation therefore experience higher levels of acetaldehyde in their systems when they consume alcohol.
When o2 supply is inadequate pyuvate is converted to?
Pyruvate is converted to ethanol in alcohol fermentation.It is converted to lactic acid in lactic acid fermentation.
