Refer to the product specific technical information sheet for the appropriate sample size and multiplying factor F or ask your technical sales representative
1. Fill the 120 mL sample bottle about half full with tap water. Next, using the 5 mL dropper, measure out appropriate sample volume of the product and add this to the water in the bottle.
2. Add 30 to 40 drops (1.5-2.0 mL) of Gardotest Indicator 195 to the bottle. Swirl to mix. The color will turn dark reddish purple.
3. Fill the 5 ml. pipette exactly to the zero mark with Gardotest Solution 90, and add this to the mixture in the bottle, a few drops at a time with swirling between additions, until the red color changes to yellow.
4. Record the number of mL used. Call this Titration T. This completes the analysis.
5. If the calculation is required, use the equation below to calculate concentration. If no calculation required, report mL of titrant used.
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.
