Both Cr 2 O 7 2 (aq) and MnO 4 (aq) can be used to titrate

Question:

Both Cr2O72–(aq) and MnO4(aq) can be used to titrate Fe2+(aq) to Fe3+(aq). Suppose you have available as titrants two solutions: 0.1000 M Cr2O72–(aq) and 0.1000 M MnO4(aq).

(a) For which solution would the greater volume of titrant be required for the titration of a particular sample of Fe2+(aq)? Explain.

(b) How many mL of 0.1000 M MnO4(aq) would be required for a titration if the same titration requires 24.50 mL of 0.1000 M Cr2O72–(aq)?
