Organic reagents in inorganic analysis

“…The alkali salts of many organic acids are used as buffers for the regulation of hydrogen-ion concentration. A characteristic example in the analysis of anions is that suggested by Kurtenacker (81,82,83) in which sulfite is masked by the addition of formaldehyde, forming sulfoxylates which are stable toward iodine, making possible an excellent iodometric titration of thiosulfate in the presence of sulfite.…”
