In addition, the first and second dissociation constants of the salicylic acid derivatives 5-nitrosalicylic acid (5-NSA), 4-hydroxysalicylic acid (4-HSA) 5-nitrosalicylic acid (5-HSA) were also determined by potentiometry. Furthermore, the second acid dissociation constants of these ligands were evaluated in I=0.1M NaClO4 ionic medium, at a temperature of 25 degrees C by computer analysis of spectroscopic data.eninfo:eu-repo/semantics/openAccessAcid dissociation constantsCatechol derivativesSalicylic acid derivativesCatecholArticle000072327400029428436214Chemistry, multidisciplinaryEngineering, chemical
