15.00 mL sample of a solution is 0.04 M in Sn2+ and xM in Fe2+. Bot

1.	15.00 mL sample of a solution is 0.04 M in Sn2+ and xM in Fe2+. Both are easily oxidised by Cr2O72− in acidic solution to Sn4+ and Fe3+ and itself reduced to Fe3+. 18.0 mL of 0.125 M Cr2O72− is required. Thus, x is:A0.410B0.205C0.820D1.640
