摘要
In this article we describe the construction of a low-cost electronic device to adapt the widespread traditional approach of Analytical Chemistry teaching into laboratory experimentation based on the guided research model. To this aim we construct a portable electronic instrument based on the Arduino microcontroller and use it to develop various experiments. This instrument has been used, but is not limited, to determine thermochemical and analytical values of various enthalpies of neutralization, to measure the stoichiometry of neutralization, and to determine the concentration of an acid of unknown concentration.
