DROP TEST CAUSTIC & TOTAL ALKALINITY

(Caustic 1 drop = 0.2 g/100 mL, > Total 1 drop = 0.265 g/100 mL)

COMPONENTS: 1 x 4029 Pipet, Calibrated 0.5 & 1.0 mL, plastic 1 x 5018 Instruction 1 x 9011 Pipet, Calibrated 0.5 & 1.0 mL, plastic w/green cap 1 x 9198G Sample Tube, Graduated, 25 mL, plastic w/cap and green dot 1 x R-0638G-C Phenolphthalein Indicator (green cap), 2 oz, DB 1 x R-0645-C Total Alkalinity Indicator, 2 oz, DB 1 x R-0709-C Hydrochloric Acid Reagent, 2 oz, DB 1 x R-0711-C Barium Chloride Solution 20%, 2 oz.

Caustic Alkalinity

1. Rinse 25 mL sample tube (#9198G) with distilled, deionized, or tap water.
2. Using a 1.0 mL pipet (#4029), add 1.0 mL washing or soaking solution. Dilute to 25 mL mark with distilled, deionized, or tap water.
3. Using a 1.0 mL pipet (#9011), add 1 dropperful (as much as can be drawn up by means of the bulb) R-0711 Barium Chloride Solution 20%. Swirl to mix.
4. Add 2 drops R-0638G Phenolphthalein Indicator. Swirl to mix. Sample will turn red if caustic alkalinity is present.
5. Add R-0709 Hydrochloric Acid Reagent dropwise, swirling and counting after each drop, until color changes from red to colorless. Always hold bottle in vertical position.
6. Multiply drops of R-0709 Hydrochloric Acid Reagent by 0.2. Record as grams/100 mL (g/100 mL) caustic alkalinity as sodium hydroxide. For practical purposes this is the same as percent.

Total Alkalinity

1. Rinse 25 mL sample tube with distilled, deionized or, tap water.
2. Using a 1.0 mL pipet (#4029), add 1.0 mL washing or soaking solution. Dilute to 25 mL mark with distilled, deionized, or tap water.
3. Add 5 drops R-0645 Total Alkalinity Indicator. Swirl to mix. Sample should turn green.
4. Add R-0709 Hydrochloric Acid Reagent dropwise, swirling and counting after each drop, until color changes from green to red. Always hold bottle in vertical position.
5. Subtract drops of R-0709 Hydrochloric Acid Reagent in Step 5 of caustic alkalinity test from drops in Step 4 of total alkalinity test. Multiply by 0.265. Record as g/100 mL total alkalinity as sodium carbonate.
