The chemical equation for the reaction of acetone with acidified potassium dichromate is: 3 CH3COCH3 (acetone) + Cr2O7^2- (dichromate) + 8 H^+ -> 3 CH3COOH (acetic acid) + 2 Cr^3+ + 4 H2O.
The chemical formula for potassium dichromate is K2Cr2O7.
No, potassium dichromate is not a hydrate. It is an inorganic compound with the chemical formula K2Cr2O7 and does not contain water molecules in its structure.
In 2 moles of potassium dichromate, there are 16 moles of oxygen atoms (from the two oxygen atoms in each formula unit). The molar mass of oxygen is 16 g/mol, so in 2 moles of potassium dichromate, there are 32 grams of oxygen.
The change in color of acidified potassium dichromate from orange to green indicates the reduction of chromium (VI) to chromium (III). This can happen when a reducing agent is introduced to the solution, causing the oxidation state of chromium to decrease and the color to change.
Sulfur dioxide gas turns acidified potassium dichromate solution green.
The oxidation number of Cr in acidified potassium dichromate (K2Cr2O7) is +6. This is because each oxygen atom has an oxidation number of -2, and the overall charge of the dichromate ion is -2.
The chemical equation for the reaction of acetone with acidified potassium dichromate is: 3 CH3COCH3 (acetone) + Cr2O7^2- (dichromate) + 8 H^+ -> 3 CH3COOH (acetic acid) + 2 Cr^3+ + 4 H2O.
The chemical formula for potassium dichromate is K2Cr2O7.
Yes, carbon dioxide gas will change acidified potassium dichromate solution from orange to green due to the reduction of the dichromate ion to chromium (III) ions in the presence of reducing agents like carbon dioxide.
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

The chemical formula for potassium aluminum dichromate is KAl(SO4)2•12H2O.
The formula is potassium dichromate.
There is not one formula for acidified potassium permanganate, it is a mixture, not a pure compound. Next to water it contains: H+ and K+ and MnO4- Warning: Do NOT use hydrochloric acid to acidify!
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.
