Chemistry Chemistry - $5 I need to plot the observed emf in mV vs logarithm of ppm F to obtain a calibration curve. From a prepared stock solution of 100 mL and the KCl molarity is 0.1M for it. From dilution of this solution, a 20 ppm, 10ppm, 5ppm, 2.5ppm, and 1.25 ppm were made. Im not sure how to go about setting this up. The weight of NaF used was 221 mg and the emf data for the dilutions are: 20ppm=276 mV , 10ppm=279 mV , 5ppm=284 mV , 2.5ppm= 289 mV , 1.25ppm=297 mV. to view the…
