The electronic spectra of 5,7-bis-metanitrophenylamino-4,6-dinitrobenzofuroxan solutions in a mixture of water-acetonitrile at a wide pH interval has been investigated. It was revealed that decreasing of pH of 5,7-bis-metanitrophenylamino-4,6-dinitrobenzofuroxan solutions in a mixture of water-acetonitrile decreases it optical density. Two isobestic points are observed. The analysis of experimental data has allowed to establish that the sample of 5,7-bis-metanitrophenylamino-4,6-dinitrobenzofuroxan has a weak acid properties.
