PEREZ-SAAVEDRA, José de Jesús; RINCON-ARCE, Sonia  e  CISNEROS-VALLADARES, Miguel Ángel. Multimeter as Alternative Measurement System in the Potentiometric Titrations. Tecnología en Marcha [online]. 2015, vol.28, n.3, pp.25-44. ISSN 0379-3982.

In this paper, we experimentally demonstrated by the statistical test Student t, the usual potentiometric titrations in analytical chemistry (acid-base, redox, complexometric and halides) can be performed using as indicator system to valuation a multimeter instead of the potentiometer. Enabling this, teaching laboratories, can be equipped at low cost with multimeters rather than potentiometers.

Palavras-chave : Potentiometric; multimeter; titrations; acid-base; redox; complexometric; halides.
