Iron in the 2 oxidation state reacts with potassium dichromate to produce Fe3 and Cr3 according to the equation: 6 Fe2 (aq) Cr2O72-(aq) 14 H (aq) <> 6 Fe3 (aq) 2 Cr3 (aq) 7 H2O(l) How many milliliters of 0.2937 M K2Cr2O7 are required to titrate 132.0 mL of 0.1782 M Fe2 solution

Given :

Volume of , V = 132 mL .

Molarity of , M = 0.1782 M .

To Find :

How many milliliters of 0.2937 M are required to titrate 132.0 mL of 0.1782 M solution .

Solution :

Moles of   :

Now , 1 mole of reacts with 6 mole of .

So , moles of required is :

Volume required is :

Hence , this is the required solution .
