A total of 17.34 mL of 0.122 M H2O2 titrant is required to completely neutralize 25.00 mL of an unknown concentration of Fe2+ in basic aqueous solution according to the generalized redox reaction formula:
H2O2(aq) + 3Fe2+(aq) --> 2OH-(aq) + 2Fe3+(aq)
What is the initial concentration of the Fe2+(aq) solution?
