According to the balanced equation shown below, 1.00 mole of oxalic acid, H2C2O4, reacts with moles of permanganate ion, MnO4-. 5 H2C2O4(aq) + 2 MnO4-(aq) + 6 H+(aq) → 10 CO2(g) + 2 Mn2+(aq) + 8 H2O(l)

The amount of iron in ore can be quantitatively determined by titrating a solution of the unknown with a standard solution of dichromate, cr2o72−. the net ionic equation is 6fe2+(aq)+cr2o72−(aq)+14h+(aq)→6fe3+(aq)+2cr3+(aq)+7h2o(aq) part a the titration of 25.0 ml of an iron(ii) solution required 18.0 ml of a 0.230 m solution of dichromate to reach the equivalence point. what is the molarity of the iron(ii) solution?
