| Abstract: | Several advanced applications of scientific graphing calculators are demonstrated. These include (a) nonlinear least squares analysis and (b) construction of titration curves for weak acids with a strong base. Stepwise instructions for obtaining the titration curves with TI-80 Series Calculators are presented. Immediate display of graphical results of a solution from a quantitative chemical problem in a classroom setting is one of the advantages of the advanced scientific calculator. |
