HI3811 CTK Alkalinity

Product information "HI3811* CTK Alkalinity"

The HANNA alkalinity test kit makes monitoring easy, quick and safe. The compact size gives the user the versatility to use the kit anywhere. The design makes the kit easy to handle and, except for alkalinity titrant, practically prevents accidental injury or damage due to spills.

Alkalinity can be measured as phenolpthalein alkalinity and total alkalinity. The phenolpthalein alkalinity is determined by neutralizing the sample to a pH of 8.3 using a dilute hydrochloric acid solution, and a phenolpthalein indicator. Since bicarbonate ions can be converted to carbonic acid with additional hydrochloric acid, the phenolpthalein alkalinity measures total hydroxide ions, but only half of the bicarbonate contribution.
