The polarographic behaviour of 7 phenylazo-4-methoxy-5-[3'-methyl-5'-pyrazolyl]-6-benzofuranol and 5 of its arylazo derivatives were investigated in wide pH range (pH 2-12). In case of the p- NO2 derivative the nitro group was shown to be reduced prior to the azo group. Satisfactor LFER was proved through E
