1. The problem statement, all variables and given/known data

For each reaction, give balanced chemical equations or NR (no reaction) and rationalize your answers in terms of trends in oxidation states. Calculate net potential for the reactions:

a) Fe2+(aq) + Co3+ (aq) (acidic conditions) →


b) CrO42−(aq) + MoO2(s) + H+ (acidic conditions) →

2. Relevant equations



3. The attempt at a solution

a) no reaction

b) 2CrO42−(aq) + MoO2(s) + 4H+ → Cr2O72- + 2H2O + Mo4+

Is this correct?

In the first case you are asked whether Co3+ is an oxidizer strong enough to oxidize Fe2+. Second question is similar.
