Abstract

Within the framework of laboratory activities relating to the teaching programof a fifth-year class of a technical school in Italy, we have determined, by the means of a spectrophotometer UV/vis, the alcoholic degree of a series of samples of Paesanella, a distillate of the family of grappa. In this experiment of quantitative analysis the students prepared anaqueous solution of ethanol to draw, by means of measurements of absorbance, the calibration line. The students found, making use of EXCEL, the linear equation with which to calculate the alcoholic degree of the samples of Paesanella.
