| For calcium chloride (CaCl2) the concentration is determined by analysing the chloride content by potentiometric titration with silver nitrate according to the following equation:

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. |
