I got 0.30 but I believe that is wrong.For each of the following experiments, try to identify the major probable sources of random and systematic errors, and consider how such errors may be minimized: 1. The iron content of a large lump of ore is determined by taking a single small sample, dissolving it in acid, and titrating with ceric sulphate after reduction of Fe (III) to Fe (II). 2. The same sampling and dissolution procedure is used as in (a) but the iron is determined colorimetrically after addition of a chelating reagent and extraction of the resulting colored and uncharged complex into an organic solvent. 3. The sulphate content of an aqueous solution is determined gravimetrically with barium chloride as the precipitant.
