How many mole of k2Cr2O7 reacted with 2 mole of (COOH)2 in acidic medium
Hello,
From the reaction below the corresponding moles can be worked out as follows:
(the plus and minus in the brackets of the reactions indicate the ions)
Cr2O7(-2)+8H(+)+3HCOOH→2Cr3(+)+3CO2+
7H20
=>3 moles of formic acid reduces = 1 mole K2 Cr2 O7
=> 1 mole of formic acid reduce = (1/3) mole K2 Cr2 O7
Ans is 1/3 mole
Hope this helps...
