Procedure:
(1) Preparation of NaCl Stock Solution
a. Prepare stock solution (1) by weighing the suitable amount of NaCl salt needed to
prepare 100 mL of 1000 ppm Na+. Use unit cancellation method in calculating the
required mass of NaCl.
b. Calculate and pipette out an appropriate volume from a stock solution (1) and
dilute to prepare 100 mL of 100ppm Na+ (stock solution 2).
c. Preparation of Calibration standards
Calibration standards are made by carrying out appropriate dilutions of the stock
solution. Concentrations of the calibration standards are selected based on the limit
of detection of the instrument in use. However, they are often in the range of 0.5, 1,
3, 5, 10, and 20 ppm for Na.
