Abstract

PROCEDIMIENTO PARA DETERMINAR LA CONCENTRACION IONICA O DENSIDAD ESPECIFICA DE UNA MUESTRA DE ANALISIS ACUOSA.COMPRENDE: A) HACER REACCIONAR A LA MUESTRA, CON UN REACTIVO ANALITICO CONSTITUIDO POR UN POLIMERO POLIELECTROLITO DEBILMENTE ACIDO CON UNA DE SUS MITADES ACIDO EN FORMA DE UNA SAL DE UN ION DE AMONIO CUATERNARIO DE FORMULA (R4N)B, EN PRESENCIA DE UN INDICADOR, PARA PRODUCIR LA FORMACION O EL CAMBIO DE COLOR, EN RESPUESTA AL INTERCAMBIO IONICO ENTRE EL POLIELECTROLITO Y LA MUESTRA; SIENDO R IGUALES O DIFERENTES, SON HIDROGENO, ALQUILO INFERIOR O ARILO; B) OBSERVAR LA FORMACION O EL CAMBIO DE COLOR; Y C) COMPARAR EL COLOR CON UNA REFERENCIA. EL POLIMERO POLIELECTROLITICO ES POLI(ACIDO ACRILICO), POLI(ACIDO MALEICO), COPOLIMERO DE ACIDO Y OTROS; EL ION AMONIO PUEDE SER TETRAMETIL-, TETRABUTIL-, TETRAETIL- Y OTROS Y EL INDICADOR ES AZUL DE BROMOTIMOL.
