HI 38013
Phenolphthalein and Total Alkalinity Test Kit

Product Description:

In this case the phenolphthalein alkalinity is determined by neutralizing the sample to a pH of 8.3 using a dilute sulfuric acid solution and a phenolphthalein indicator. Since bicarbonate ions can be converted to carbonic acid with additional sulfuric acid, the phenolphthalein alkalinity measures total hydroxide ions, but only half of the carbonate contribution. 

Order Information:

HI 38013 test kit comes with 10 mL phenolphthalein indicator, 10 mL bromophenol blue indicator, 105 mL alkalinity reagent (2), 20 mL calibrated plastic vessel with cap and 1 mL syringe with tip.
