The use of linear methods to characterise the acidity of rains is presented. The acidity constant and the concentration of some rain samples collected in the city of Tirana, Albania, were determined using potentiometric measurements with a pH glass electrode. The concentration and the acidity constant were determined using linearised pH-metric titration and multiple sample additions. Being more sensitive to the acid and base impurities, strong deviations from linearity were observed during linearisation of the multiple sample addition. Better results were obtained from the linearisation of titration method. Nevertheless, the use of corrected linear plots would be of interest to determine the concentration and the acidity constant of weak acids present in rain, rivers and lakes.
