PROCEDURE
1.
Obtain a fresh sample of the dipping solution. Every attempt should
be made to carefully mix the dipping solution prior to sampling to
insure that a representative sample is obtained.
2. The red taped syringe is the sampler. Insert this 1.0 mL syringe into
the sample. Depress the plunger of the syringe to expel air.
Withdraw the plunger until the bottom of the plunger is opposite
the 0.5 mark on the scale.
NOTE:
A small air bubble may appear in the Titrator barrel. Expel
the bubble by partially filling the barrel and pumping the solution
back into the sample. Repeat this pumping action until the bubble
disappears.
3. Completely empty the contents of the syringe into the test tube.
4. Fill the test tube (0778) to the 10 mL line with clean tap water or
distilled water.
5. Add 5 drops of 1.0N *Sodium Hydroxide Solution (4004).
6. Add 7 drops of the *PQ-80 Indicator Solution (6413) to the
sample. Cap the tube and swirl to mix. A brown color will develop.
