The soil is digested in concentrated sulfuric acid, in the presence of a catalyst mixture that allows the boiling temperature to be regulated, until complete dissolution and oxidation. The organic N contained in the sample is oxidized to ammonium (as ammonium sulphate). The NH 4

filestore.aqa.org.ukThe iron content of iron tablets can be determined by colorimetry. Method: • Dissolve a tablet in sulfuric acid . • Oxidise all the iron from the tablet to Fe; 3+ (aq). • Convert the Fe; 3+ (aq) into a complex that absorbs light of wavelength 490 nm • Make the solution up to 250 cm; 3
