Description

Powder Pillows Packaged Powder Reagents, Bromocresol Green - Methyl Red Indicator (94399) from Hach. Designed for use with test kits and Hach handheld digital titrator.

Powder Pillows reagent pouches are hermetically sealed in foil pouches for a long shelf life.

Summary of method: A phenolphthalein indicator is added to the sample. Then, the sample is titrated with a sulfuric acid solution. The phenolphthalein indicator changes color at the endpoint pH of 8.3. This value indicates the phenolphthalein (P) alkalinity and is a measure of the total hydroxide and one-half of the carbonate in the sample. A bromcresol green-methyl red indicator is added and the titration continues to the second endpoint at a pH between 4.3 and 4.9. This value indicates the total (T) alkalinity and is a measure of all carbonate, bicarbonate and hydroxide in the sample. The endpoint pH is determined with color indicators or with a pH meter.
