The same method as described by the calibration method. Tablet solution : The solution was prepared following the method described in the calibration method by reacting tablet with NaOH and finally diluting to 250.0 mL. Use this data to prepare the standard addition curve. Please remember to find the concentration of each standard solution in the volumetric flask before you plot the data.
