Calcium Chloride Analysis
Tetra Technologies
For calcium chloride (CaCl2) the concentration is determined by analysing the chloride content by potentiometric titration with silver nitrate according to the following equation:

Calcium Chloride Analysis

The concentration of silver ions is followed by a sliver electrode. The analysis is carried out in acidic aqueous solution. Concentration of CaCl2 in the original sample is then calculated from the chloride concentration.

Normal Measuring Range 30-100% CaCl2
Quantification Limit 10%
Tolerance +/- 0.9% (95% confidence interval)

An alternative approach is to utilise EDTA-titrations with a suitable indicator and visual endpoint determination.
