The amount of chlorine (X), expressed as % sodium chloride is calculated by using the following formula:

X=5,845×V1−V2m

where:

V1
  • ml of silver nitrate solution 0,1 mol/l added

  • V2
  • ml of ammonium thiocyanate solution 0,1 mol/l used for titration

  • m
  • weight of sample.

  • If the blank test indicates that silver nitrate solution 0,1 mol/l has been consumed deduct this value from the volume (V1 – V2).
