A 100.0-mL sample of spring water was treated to convert any iron present to Fe. Addition of 25.00-mL of 0.002517 M K₂Cr₂O, resulted in the reaction 6Fe²+ + Cr₂O + 14H* 6Fe³+ + 2Cr³+ + 7H₂O The excess K₂Cr₂O, was back-titrated with 8.53 mL of 0.00949 M Fe²+ solution. Calculate the concentra- tion of iron in the sample in parts per million.
