Standardization of benzethonium chloride standard solution | Autotitrator COM-A19
The determination method of anion surfactant uses a cation surfactant, with an opposite charge, as the titrant. The end point is the point at which the charge becomes neutral due to the reaction between the anion and the cation. Benzethonium chloride is used as the cation standard solution.
This report introduces a method for standardization of benzethonium chloride standard solution. Sodium dodecyl sulfate is used for standard solution. First, determine the purity of sodium dodecyl sulfate. Add diluted sulfuric acid to sodium dodecyl sulfate, heat to reflux, and then titrate with sodium hydroxide standard solution.
Subsequently, prepare the standard solution of sodium dodecyl sulfate whose purity has been determined, and standardize the benzethonium chloride standard solution with titration against sodium dodecyl sulfate standard solution.

Quantitative determination of sodium sulfate in bath additive | Autotitrator
The precipitation titration using lead ion-selective electrode achieves the measurement of sulfate ions. Lead sulfate is generated by adding lead nitrate to sulfate ion. The potential reading with lead ion-selective electrode differs depending on the concentration of sulfate ion in sample solution. The maximum change in potential is observed when it reaches the equivalent point of sulfate and lead ions. The concentration of sulfate ion is determined by the titrant volume consumed until it reaches the inflection point.
SO₄²- ＋ Pb(NO₃)₂ → PbSO₄ ＋ 2NO₃-
This report introduces an example of the measurement for sulfate ion in bath additive with using lead ion-selective electrode.

Determination of anion surfactant in detergent | Autotitrator
The determination method of anion surfactant uses a cation surfactant with an opposite charge as the titrant. The end point is the point at which the charge becomes neutral due to the reaction between the anion and the cation. Benzethonium chloride is used as the cation standard solution.
