im not really sure how to work it but just by looking at the choices give, choice C is the only answer that has a balanced +6 charge on both sides...question is below:
during a titration it was determined that a 30ml of a .1 M Ce^4+ solution was requred to react completely with 20ml of a .15 M Fe^2+ solution. which one of the following reactions occured?
answer = Ce^4+ + Fe^2+ --> Fe^3+ + Ce^3+
