Note

Calculation of Results

FORMULA:    ppm sulfite as SO3  = ml  of potassium iodide-iodate (RXSOL-62-5503-006)  x       500    /  ml SAMPLE  

                        Using a 50 ml sample, sulfite, in parts per million as SO3  is equal to the ml of  RXSOL-62-5503-006 required multiplied by 10. 


Example:
A 50-mL sample was titrated with 0.0125 N titrant and 6 mL of titrant was used at the endpoint. The concentration is 6 mL × 10 = 60 mg/L sulfite SO3 2–
