If the tablet containing ferrous fumarate is analyzed for its iron (Fe2+) content using the permanganate titration method, the answer would be too high than it should actually be.
This is because the fumarate ions would also be consuming the permanganate moles in a similar way that Fe2+ ions would be consuming, and we won't be able to differentiate between the two. So we would just see that more moles of permanganate are consumed to reach the end point, and based on this observation we would make a conclusion that equivalently that many moles of Fe2+ must have been present. But this is not true because a portion of the moles of permanganate consumed also comes from consumption by fumarate ions.
So the results in this case would be erraneously high.

Considering that fumarate ion can also be oxidized by permanganate, what problem might you encounter if...

Vitamin C can be measured using a technique called titration. Because vitamin C is easily oxidized, we can use this chemical reactivity to detect it in solution. If we react vitamin C with iodine, the vitamin C is oxidized and the iodine is reduced. Iodine (12 molecules) form a purple complex with starch in solution, but reduced iodine, iodide, (I-) is colorless in the presence of starch. CH,OH CH,OH о о снон Η...

LAB DESCRIPTION: In aqueous solutions the Ni2+ cation forms a complex ion with 6 H2O ligands. The formula of this complex ion is: Ni(H2O)62+. When this complex ion is mixed with aqueous NH3 a reaction occurs where some of the H2O ligands are displaced with NH3 ligands. But how many of the H2O are displaced by NH3? In this experiment you will mix nickel(II) sulfate and aqueous ammonia to synthesize a compound containing a complex ion whose formula is Ni(H2O)6-x(NH3)x2+,...

This is a special order problem that also requires that you use the high low method to estimate some cost function parameters, so you may want to review the high-low method lectures in Module 1. As with almost all of the analyses that we have done, determining variable and fixed costs, and knowing what to do with them, is critical. Huang Automotive is presently operating at 75% of capacity.
