K2Cr2O7 + Na2C2O4 --> K2C2O4 + Na2Cr2O7
acetone does not react with potassium dichromate
No reaction.
It will be a ketone attached to the second carbon of the propanol (in place of the OH) if treated with a mild oxidant.
The chromium in dichromate (Cr2O72-) is reduced from chromium(vi) to chromium(iii) (Cr3+). The former is lemon orange and the latter is green. It's a redox reaction so yuo'll need an reductant to perform this reaction.
K2Cr2O7 + 5HNO3 = 2KNO3 +Cr2(NO3)3 +5/2H2O + 9/2[O]

http://wiki.answers.com/What_is_the_word_equation_for_the_reaction_of_sulphur-di-oxide_with_acidified_potassium_dichromate
I think the reaction equation can be written as follows: K2Cr2O7 (aq) + BaCl2(aq) ------ BaCr2O7(s) + 2KCl(aq).
3 K2Cr2O7 + 2 (NH4)3PO4 ------------3 (NH4)2Cr2O7 + 2 K3PO4
Any reaction occur.
chromic acid
by the reaction of lead nitrate with potassium chromate or potassium dichromate
ethanol is converted into acetic acid....
There is no reaction
Cr2O72- + 6Fe2++ 14H+ --> 2Cr3+ + 6Fe3+ + 7H2O
