TITULACIONES ÁCIDO-BASE: POTENCIOMETRICAS A MICROESCALA TOTAL CON MICROSENSORES DE pH Y DE REFERENCIA DE BAJO COSTO

Abstract

In th is work a low co s t h om e -m a d e micropotentiometric cell is built based on a W° pH microsensor and Cu | Cu(II) | H 2 0 | | cuasireference microelectrode. Alinear Nikolsy type response is obtained, E = 54.89 mV - 49.79 pH; r 2 = 0.9889. E = f (v o lum e ) and its corresponding pH=(volume) plots are shown for standard Solutions.
