Calibration standards.Transfer 1.00, 5.00, 10.00, 15.00 and 20.00 mL aliquots of 10ppm F- solution to 100 mL flasks. Add 50 mL of TISAB containing CDTA to each. Dilute to the mark with DI water and mix thoroughly. Calculate the exact concentration of F- in each calibration standard.
So what would the calculations set up and answers be to find the concentration of F- in each standard.
