Product description
To determine iron (III) in concentrated sulfuric acid in the form of sulfosalicylate, the sample is placed in a 100.0 ml flask, the necessary reagents are added and water is added to the label. The absorbance at 420 nm e = 6.0 * 10 ^ 3 and the cell thickness l cm is measured.
Calculate the weight of the sample for analysis if the optimum optical density is 0.435.
Option 3: w (Fe (III) = 0.010%, l = 1 cm
