Titer of H2SO4 using Na2CO3 as per European Pharmacopoeia EP
H2SO4 also known as oil of vitriol is described as the king of chemicals because of its versatility and high reactivity. Owing to its versatility it is used extensively in industries and therefore its titre determination is a frequent process. European Pharmacopoeia describes the method for titer determination of H2SO4 using Na2CO3 with colorimetric titration using a color indicator. This application gives the use of potentiometric sensor in the determination of the titer value without changing the method. The use of heater DH100 for complete removal of CO2 after the first equivalence point leads to very high precision results. Depending on instrument type, manual operation and method, changes can be made using the given method as a reference. Reaction: 1) 1st EQP: H2SO4 + Na2C03 → NaHCO3 + NaHSO4 2) Heating 3) 2nd EQP NaHCO3 + NaHSO4 →H2O + CO2 + Na2SO4 It is observed that for higher concentration without heating the solution after the first equivalence point, carbon dioxide was evolved and second equivalence point was detected. The application has been developed for the use of a potentiometric sensor instead of color indicator as given by the original method for colorimetric titration.

Determination of Water Content in Acetone
A volumetric Karl Fischer titration is a classical titration method which uses a mixture of I2 and SO2 dissolved in a suitable solvent to determine the water content in a sample. CH3OH + SO2 + 3RN + I2 + H2O → (RNH)2.SO4CH3 + 2(RNH)I Volumetric Karl Fischer titration is used to determine the water content in ketones. Ketones such as acetone react with methanol forming ketals. In this reaction water is released as a byproduct. R-CO-R + 2CH3OH → RC(OCH3)2-R + H2O To avoid this side reaction, special reagent called K-reagent is used. Ketones form a major constituent of paints, lacquer, explosives etc. These ketones should be completely free from water. The water content has to be detected precisely before ketones are further used. This application note demonstrates volumetric Karl Fisher titration for the detection of water in ketones.

Blank Value and Bromine Index Determination According to ASTM D1492-08 / M399
Blank value and Bromine Index determination are determined in cyclohexene and in diluted gasoline solution using a single titration method by coulometry according to ASTM D1492-08. This standard is applied to aromatic hydrocarbons with traces of olefins (alkenes) having Br-Indexes below 500.
Calcium Content in Slim Milk

M718/The calcium content in slim milk was determined by multiple standard addition technique using the direct sample preparation method.

Water in Edible Fats, Oils and Dairy Products
This application is used to determine the water content in edible fats, oils and dairy products by volumetric Karl Fischer titration.
Reducing Sugars according to Rebelein: Back Value
This application is used to determine the Back (Fehling) value of the Fehling solution that is used to oxidize the reducing sugar in beverages. Liberated iodine is titrated with sodium thiosulfate (Na2S2O3) titrant and the titration is monitored by potentiometric measurement with a Platinum sensor. The titration curve is evaluated at the inflection point to determine the equivalence point (EQP).
Acid number blank value determination by endpoint titration
This application is used to determine the blank value of the solvent mixture used for acid number determination. The titration is monitored by potentiometric measurement with a pH sensor and terminated at a pre-defined potential, the end point (EP).
Optimizing Automated Water Content Determination with a Karl Fischer Water Standard
Method for volumetric KF titration of a 5.55% oven water standard.
Reducing Sugars According to Rebelein: Sample Determination
This application is used to determine the content of reducing sugars in alcoholic (wine) and non-alcoholic (juices) beverages according to Rebelein. The reducing sugars are oxidized with an excess of alkaline copper sulphate (CuSO4) solution (Fehling solution), where Cu(II) is reduced to Cu(I). The addition of iodide reduces the remaining excess of Cu(II). Iodine is formed which is titrated with sodium thiosulfate (Na2S2O3) titrant and the titration is monitored by potentiometric titration with a Platinum sensor. The titration curve is evaluated at the inflection point to determine the equivalence point (EQP).
Vitamin C and Reducing Components in Beverages
This application is used to determine the Vitamin C content and reducing components in beverages. The sample is titrated with iodine and monitored by potentiometric measurement with a Platinum sensor. The steepest inflection of the titration curve is evaluated to determine the equivalence point (EQP).
Vitamin C content in beverages Using Autotitrator
This application is used to determine the Vitamin C content in beverages. The sample is titrated with Diphenylindophenol (DPI) titrant monitored by voltametric indication with a current-polarized double pin Platinum sensor. The endpoint of the titration is determined by evaluation of the steepest change of the titration curve.
Water Determination In Petrochemical Products
This application gives an automated method to determine the water content in petrochemical products by volumetric Karl Fischer titration.
Acid Content By Equivalence Point Titration
This application is used to determine the acid content of various aqueous solutions by titration with NaOH titrant. The titration is monitored by potentiometric measurement with a pH sensor and the titration curve is evaluated at the inflection point to determine the equivalence point (EQP).
Acid Content by Endpoint Point Titration
This application is used to determine the acid content of various aqueous solutions by titration with NaOH titrant. The titration is monitored by potentiometric measurement with a pH sensor and terminated at an endpoint (EP) of pH 7.
Base content by equivalence point titration
This application is used to determine the base content of various aqueous solutions by titration with HCl. The titration is monitored by potentiometric measurement with a pH sensor and the titration curve is evaluated at the inflection point to determine the equivalence point (EQP).
Titer of di-sodium dichromate Na2Cr2O7 0.1 mol/L
This application is used to standardize 1/6 Na2Cr2O7 titrant with Ammonium ferrous sulfate. The titration is monitored by potentiometric measurement with a Platinum sensor and the titration curve is evaluated at the inflection point to determine the equivalence point (EQP).
