www.cdc.govFormic acid has been determined by this method [3]. INTERFERENCES: Particulate salts of all the acids will give a positive interference. Chlorine or hypochlorite ion interfere with chloride determination and bromine interferes with bromide. Silica gel will collect ca. 30% of the free Cl. 2. and Br. 2. in an atmosphere [4].
