|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.

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