A series of solutions is used to plot a standard curve that is then used to find parameters about an unknown. In the experiments conducted in this course, we plotted absorbance vs. concentration. In a General Chemistry lab (not limited to Chemistry 105), which of the following is not a typical calibration plot? Select one: a.Precipitating mass vs amount of titrant added b.Intensity of color vs concentration c.Concentration vs volume of vessel d.Electrical conductivity vs concentration
