A total of 17.34 mL of 0.122 M H202 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 + _ Fe2+ --> _OH- + __Fe3+ (all are aqueous states)
Question: Based on the balanced form of this redox reaction formula, what is the initial concentration of Fe2+ aqueous solution?
