Aplicação de um corante tiazolilazo como indicador ácido-base e determinação das suas constantes de ionização ácida Application of a thiazolylazo dye as an acid-base indicator and determination of its acid ionization constants
<abstract language="eng">The pKa values of the 6-[2´-(6´-methyl-benzothiazolylazo)]-1,2-dihydroxy-3,5-benzenedisulfonic acid (Me-BDBD) have been determined at 25 °C, in 0.10 mol L-1 NaCl medium by spectrophotometric method. The SQUAD computer program was used to process experimental...
