What is the balanced equation for potassium dichromate and ethanol?
The balanced equation for the reaction between potassium dichromate (K₂Cr₂O₇) and ethanol (C₂H₅OH) in an acidic medium is: [ K_2Cr_2O_7 + 3 C_2H_5OH + 8 H^+ \rightarrow 2 Cr^{3+} + 3 CH₃COOH + 2 K^+ + 7 H₂O ] This reaction involves the reduction of potassium dichromate and the oxidation of ethanol to acetic acid.
Is a compound A. ethanol B. carbon C. helium D. potassium?
Ethanol is a compound. The others are elements.
What chemical reaction occurs during the Breathalyzer?
During a Breathalyzer test, the chemical reaction that occurs is the oxidation of ethanol (alcohol) in the breath. The device typically uses an oxidizing agent, such as potassium dichromate, which reacts with the ethanol to produce acetic acid and chromium ions. This reaction changes the color of the solution, and the extent of the color change is proportional to the concentration of alcohol in the breath, allowing for the determination of blood alcohol content.
What is balanced equation for reaction which methane obtained by reduction of chloroform?
The balanced equation for the reaction where methane is obtained by the reduction of chloroform is: 2CHCl3 + 6Zn -> 2CH4 + 6ZnCl2. This reaction involves the reduction of chloroform (CHCl3) using zinc (Zn) metal to produce methane (CH4) and zinc chloride (ZnCl2).
CH3 plus CH3CH2OH what is the expected product?
The reaction between CH3 and CH3CH2OH (ethanol) is a radical substitution reaction. The expected product would be ethane (CH3CH3) and a ethoxy radical (CH3CH2O•).
What is the reaction between potassium carbonate and Ethan?
When potassium carbonate reacts with ethanol (Ethan), it will undergo a metathesis reaction, where the potassium ion will replace the hydrogen in the ethanol molecule. This will result in the formation of potassium ethoxide and water. The balanced chemical equation for this reaction is: K2CO3 + 2C2H5OH -> 2KC2H5O + H2O
What is the balanced equation for potassium dichromate and ethanol?
The balanced equation for the reaction between potassium dichromate (K₂Cr₂O₇) and ethanol (C₂H₅OH) in an acidic medium is: [ K_2Cr_2O_7 + 3 C_2H_5OH + 8 H^+ \rightarrow 2 Cr^{3+} + 3 CH₃COOH + 2 K^+ + 7 H₂O ] This reaction involves the reduction of potassium dichromate and the oxidation of ethanol to acetic acid.
What is the reaction between acidified potassium dichromate and ethanol?
When acidified potassium dichromate is reacted with ethanol, the dichromate ion (Cr2O7^2-) is reduced to chromium(III) ion (Cr^3+). This reaction results in the formation of green chromium(III) sulfate (Cr2(SO4)3), with ethanol being oxidized to acetic acid.
Does the colour of potassium permanganate persist when it is added initialy to heated 3ml of ethanol?
When potassium permagnate is added initially to ethanol, ethanol gets oxidised into ethanoic acid using potassium permagnate. Thus, decolorizing potassium permagnate. When excess is added , the color of potassium permagnate persists.
What is the correctly balanced equation for a combustion reaction between liquid ethanol and oxygen gas?
Under ideal circumstances the following:C2H6O + 3 O2 ---> H2O + 2 CO2it's real simple once you know the products
Why does the color of potassium permanganate not disappear when excess of ethanol is added to it?
The color of potassium permanganate does not disappear when excess ethanol is added because ethanol is unable to fully reduce the permanganate ion (MnO4-) to colorless manganese dioxide (MnO2). Ethanol is a weak reducing agent and is not capable of completely reducing the permanganate ion in this reaction. Additionally, the reaction between potassium permanganate and ethanol is not stoichiometric, meaning that there is an excess of one of the reactants, which can also contribute to the color persisting.
What is the equation for the reaction of CH3CH2MgBr with methanol?
The reaction between CH3CH2MgBr (ethylmagnesium bromide) and methanol results in the formation of ethanol and magnesium bromide. The balanced equation for this reaction is: CH3CH2MgBr + CH3OH -> CH3CH2OH + MgBr2
What is reaction between C2H5OH and O2?
The reaction between C2H5OH (ethanol) and O2 (oxygen) is combustion, which produces carbon dioxide (CO2) and water (H2O) as products. The balanced chemical equation for the reaction is: C2H5OH + 3O2 → 2CO2 + 3H2O
Why the color of potassium perpanganate disappears if it is added to warm solution of ethanol?
When potassium permanganate reacts with ethanol, it releases oxygen. ie, an atom of oxygen thus converting the ethanol to acetic acid. Initially colour disappears because coloured permanganate ions of potassium permanganate are consumed to oxidise ethanol. C 2 H 5 OH (WITH ALKALINE KMnO 4) CH 3 COOH+H 2 O Remember :When excess is added colour does not change because there is no more alcohol left and hence there is no reaction.
Chemical formula for the reaction of ethanol and lucas reagent?
The chemical formula for the reaction of ethanol with Lucas reagent (concentrated HCl and ZnCl2) is C2H5OH + HCl → C2H5Cl + H2O. This reaction converts ethanol into ethyl chloride by substitution of the hydroxyl group with a chlorine atom.
What is the balanced combustion reactions for liquid ethanol?
Combustion of Ethane: 2C2H6+7O2-->4CO2+6H2O Combustion of Ethanol: C2H5OH+3O2-->2CO2+3H2O
What is chemical equation ethyl iodide plus aq.KOH?
The chemical equation for the reaction between ethyl iodide and aqueous potassium hydroxide is: C2H5I + KOH → C2H5OH + KI This reaction involves the substitution of the iodine in ethyl iodide with hydroxide from KOH, resulting in the formation of ethanol and potassium iodide.
