Easy determination of chloride
Solving the analysis of chloride without ion-selective electrodes or reference electrodes, which are expensive, of limited life span, sensitive to light and easily fouled
The traditional titrimetric method for the determination of chloride has employed silver nitrate as titrant Automated potentiometric methods use an ion-selective chloride electrode to detect the endpoint
These electrodes are expensive, of limited life span, sensitive to light and easily fouled.
Moreover, they require the use of reference electrodes whose liquid junction is also easily fouled.
Multitrator's thermometric titration technology offers a much simpler solution to the analysis of chloride.
The reaction enthalpy of silver and chloride ions is a high -66kJ/mol (compared with that for the reaction of a strong acid with a strong base of approximately -55kJ/mol).
This allows chloride to be analysed accurately down to 20mg/l, and Multitrator has demonstrated this in analysing a range of bottled and natural waters.
