The balanced equation for the reaction between potassium dichromate (K2Cr2O7) and ethanal (CH3CHO) in an acidic medium is:
[ \text{K}_2\text{Cr}_2\text{O}_7 + 3 \text{CH}_3\text{CHO} + 4 \text{H}_2\text{SO}_4 \rightarrow 2 \text{Cr}_2\text{(SO}_4\text{)}_3 + 3 \text{CH}_3\text{COOH} + K_2\text{SO}_4 + 4 \text{H}_2\text{O} ]
In this reaction, potassium dichromate is reduced to chromium(III) sulfate while ethanal is oxidized to acetic acid.

What is the chemical formula for ethanal?
The chemical formula of ethanal (acetic aldehyde) is CH3CHO.
Ethanal to acetaldehyde?
Ethanal and acetaldehyde are different names for the same compound, which has the chemical formula CH3CHO.
Is ethanal soluble in water?
Yes, ethanal (acetaldehyde) is soluble in water. This is because ethanal can form hydrogen bonds with water molecules due to the presence of a polar carbonyl group, making it miscible in water.
Main reason for the difference in boiling points of Methanal and Ethanal?
The main reason for the difference in boiling points between methanal (formaldehyde) and ethanal (acetaldehyde) is the difference in molecular weight and size. Ethanal has a larger molecular size and weight compared to methanal, which leads to stronger intermolecular forces such as van der Waals forces, resulting in a higher boiling point for ethanal.
Is ethanal a liquid?
Yes, ethanal (also known as acetaldehyde) is a colorless, flammable liquid at room temperature. It has a strong, distinctive odor and is commonly used in the production of chemicals and plastics.
What is the reaction between glucose and acidified potassium dichromate and Chemical Equation?
The reaction between glucose and acidified potassium dichromate is the oxidation of glucose to form gluconic acid. The chemical equation for this reaction is: C6H12O6 + H2Cr2O7 + H+ -> C6H11O7COOH + Cr2(SO4)3 + H2O
Why is ethanal can react with acidified potassium dichromate but propanone cannot?
because apparently, propanone is a ketone, and ketons do not have a hydrogen which could get oxidised, unlike aldehydes which do.
How would you convert ethanal into propanone?
To convert ethanal (acetaldehyde) into propanone (acetone), you can perform an oxidative reaction. One common method is to first oxidize ethanal to acetic acid using an oxidizing agent like potassium dichromate or chromium trioxide, followed by a further oxidation step to convert acetic acid into propanone, typically through a process like thermal decarboxylation or by using a strong dehydrating agent. Alternatively, you can also achieve this transformation via a condensation reaction of ethanal followed by rearrangement, but the oxidative route is more straightforward.
What is the half equation of ethanol to ethanoic acid?
The half equation for the conversion of ethanol to ethanoic acid involves the oxidation of ethanol to form ethanal (acetaldehyde), followed by the further oxidation of ethanal to ethanoic acid. The half equation for the oxidation of ethanol to ethanal is: CH3CH2OH → CH3CHO + 2H+ + 2e-. The half equation for the oxidation of ethanal to ethanoic acid is: CH3CHO + H2O → CH3COOH + 2H+ + 2e-.
