Volumetric analysis?
A sample of iron ore are weighing 1.1255g(rams) is dissolved. All the iron is reduced to FE2+ and the soulution is titrated with 0.1520 N(ormality) KMnO4. Calculate the % Fe2O3 in the sample. (amount of KMnO4 used is 42.0 mL)
Hint: Fe2O3 --> FeO

Volumetric Analysis question?
A 0.5500g sample of impure MgO is titrated with HCl of which 2.5 mL= 0.0650g of CaCO3. The endpoint is over-stepped on the addition of 50 mL of the acid, and the solution becomes neutral on the further addition of 2.35 mL of 0.3800N NaOH. What is the %MgO in the sample?
