Hello i am studying Cape Chemistry (carribean Advanced Proficiency), i do believe this is equivalent to Secondary 3 & 4 chemistry. My question is how would you find the iron percentage found in a tablet, Do we use displacement reactions to get iron by itself and find the mass of that iron displaced?

Dear Justin Smith,
I believe you have answered your own question correctly. We need to remove iron from the tablet and based on secondary level limited chemistry knowledge, we can only think of displacement reaction by using a more reactive and suitable metal such as zinc to react with compounds of iron in the tablet. Zinc being more reactive than iron will displace iron from compounds of iron. Then, we can measure the mass of iron that is displaced and collected. Subsequently, we can then calculate the percentage mass of iron in the tablet by dividing the mass of iron over the total mass of the tablet and multiply by 100%. Hope my explanation is helpful. Kudos!
