Ultramicrovaloración potenciométrica de sulfato ferroso amoniacal con tres diferentes oxidantes

A potentiometric Ultramicrotitration (titration of 0.2 mL) of ammoniacal ferrous sulfate with three different oxidants (potassium dichromate, potassium permanganate and ceric sulfate) was compared to the conventional potentiometric titration of the above reagent. This article compares the Ultramicrotitration against the conventional one, uses less than 2% of the reagents, consequently decreasing costs and waste in similar proportions. The optimization of resources, expenses and waste motivates an “ecological conscience” in both instructors and students that may also positively impact current industry standards.
