Refer to the product specific technical information sheet for the appropriate sample size and multiplying factor F or ask your technical sales representative
Procedure
| 1. Using one of the 5 mL Droppers, pipette 10 mL of sample solution into the 250 mL Erlenmeyer Flask. Add water to dilute the sample volume to the 100 mL mark. Swirl to mix. 2. Using the other 5 mL Dropper, pipette 10 mL of Gardotest Solution 10 (20% Potassium Fluoride) into the diluted sample solution in the flask. Swirl to mix. 3. Add 5-10 drops of Gardotest Indicator 2 (Phenolphthalein) and swirl to mix. There will be no color change. |
4. Fill the calibrated pipette exactly to the zero mark with Gardotest Solution 37 (1.0 N Sodium Hydroxide) and add this to the mixture in the flask a few drops at a time with swirling between additions, until the color of the solution turns a distinct pink. Record the number of mL used. Call this Titration T. This completes the analysis. CALCULATION TF = vol % (or oz/gal) of respective BASF Chemetall Americas product. T is the number of milliliters used of the titrant to reach the end or equivalence point. F is the multiplying factor found in the technical data sheet for the respective product being analyzed. For Deoxidizer LNC, the factor is actually 2.4 Simply multiplying the milliliters of the titrant used to reach your equivalence point by the factor 2.4 will give you your volume percent of Deoxidizer LNC in soulution. |
