1. Fill the test jar to the 20 ml mark with cooled sample.
2. Add 4 drops of reagent PA1. The sample should turn pink. If it does not, terminate the test and report a result of zero.
3. Add drops of reagent PA2 one at a time with gentle mixing until the pink colour disappears. Count the number of drops used.
4. Each drop is equivalent to 40 mg/l P-alkalinity, expressed as CaCO3.
5. Retain the sample after the alkalinity test as this may be used for the chloride determination if required.
6. Total alkalinity (as CaCO3): for total alkalinity, replace reagent PA2 with TA4 in step 2. Colour change in step 3 is from blue to orange.
